I'm back and would like to continue this discussion. Keep in mind that I would like to make a video of this for Therian Nation. I have looked at all the responses and looked more deeply into a few possibilities, so here's an updated list.
Animal-hearted/Other-hearted/Kith
People can obviously feel deeply connected with animals without identifying as nonhuman. Some Animal-hearted people do claim to have shifts similar to Therians.

Copinglink/Otherlink
Therianthropy (and a therioside) is an innate part of us that is not consciously chosen. Copinglinks and Otherlinks knowingly create nonhuman personas as coping mechanisms or various other reasons.

Roleplay/Experience Taking
It's fun to create characters and act out being someone or something else. This can be a positive interest or outlet. It's easy to feel connected to anthropomorphic characters. Mimicking these characters and their animal behavior can and does occur. Experience taking can happen without a person realizing it; however, it's usually temporary. Therianthropy and Otherkinity are permanent identities, not hobbies.

Power Animals/Spirit Animals/Guides/Totems
"Everyone is thought to have a few of these guardian power animals, from childhood on. Over the course of her or his life the person may have several." (
https://www.shamanlinks.net/shaman-info/the-spirit-world/power-animals/ )
Power animals are external, independent entities that can guide us through challenging events in life. They are not limited by the physical world and may choose to speak to you. Others are more cryptic and will use symbology. It depends on what you need. It is possible that working with a power animal can cause shift-like experiences that leads one to feel like an animal. These encounters should not be taken lightly and should be respected due to the connection to Shamanic and Aboriginal cultures across the globe.
In comparison, theriosides are the inner animal self. They are based on real-world animals and should not be able to speak to you or carry on conversations. I've worked with spirit guides and teachers myself, and for me personally those experiences differ from Therianthropy.
Daemon
The following comes from The Daemon Page website.
A daemon is a personified version of the second half of someone's mental dialogue, usually mentally represented in an animal form. Usually has a name, gender and personality; usually the dæmon's personality is at least somewhat different from that of the person.
Daemons are considered to be "mental constructs" instead of spiritual entities. Mental consturct means "The idea that dæmons are something that people "do" with their minds, rather than something that exists objectively and independently of us." They can be spoken to, and they can speak back to you. Daemons can change form or shape until they become stable, but some remain fluid.
Those of us who call ourselves "dæmians" have taken [Phillip] Pullman's wonderful dæmon concept (His Dark Materials) and turned it into a fun - and even useful - mental construct. For us, dæmons are a part of our consciousness that we've assigned a name, gender, and symbolic animal form. They're glorified imaginary friends that act as the other side of our mental dialogue - sometimes being the voice of reason, devil's advocate, or just a friend. Simply put, dæmons play the role of constant mental companion.
Daemians, people who enjoy daemonism, do not believe they are an animal like Therianthropes do. They do not identify as a nonhuman species. It is highly possible that a lot of people are actually creating daemons and then tricking themselves into having shift-like sensation and feeling nonhuman.

Tulpa
The tulpa itself may not cause a person to feel nonhuman, but it could be possible for a person to create an animal tulpa and misidentify it as a therioside. This could easily lead them to confuse normal behaviors and sensations with being nonhuman. Whereas a therioside usually merges and integrates with the humanside of us, a Tulpa becomes more and more independent and separate.
The most general definition as accepted by the Western tulpamancy community is as follows: A tulpa is a thought-form that is imagined into existence. It is a sentient and autonomous mental companion. Tulpas are–or resemble to an indistinguishable point–a second consciousness co-inhabiting a brain with their creator. Upon creating a tulpa, the creator, or “host” will essentially share their head and their life with another person. They are distinct from the host in that they possess their own personality, opinions, and actions, which are independent of the host’s, and are conscious entities in that they possess awareness of themselves and the world.
Tulpamancy is a branch of the wider phenomenon of plurality. Plurality is an umbrella term encompassing all phenomena where multiple consciousnesses coinhabit a brain. It should be noted that Western tulpamancy is a practice that is wholly different from the original practice in Tibetan Buddhism. Tulpas are now created for a variety of reasons, some similar and many very different from the reasons of Buddhism and occultism–curiosity, understanding the brain and the nature of selfhood, inspiration, and, most commonly, companionship." The Western tulpamancy community does not believe that the tulpa can physically manifest.

Interacting with/Observing an Animal
When we are around animals often, we can begin to unintentionally mimic them. Veterinarians, animal handlers, and researchers may need to think like those animals in order to treat, train, and study them. For some people, it's possible that they may temporarily feel more animal-like than human. This can also happen to children who are raised around animals. Some imprinting may happen, but most children grow out of it. However, it is possible that imprinting on a nonhuman animal could lead to Therianthropy in some cases.

Basically, TG has a much higher % of LGBT+ than the general population. I've heard LGBT+ people mention that they once believed themselves to have a non-human identity, because of how alien they felt within their bodies.
Do you think it's possible that some people think of themselves as therian, but are in fact only LGBT+?
Still undecided if this should be included given the current situation of discontent between the two communities. Perhaps some more input will help.
Medical/Psychological Conditions/Other
The following can cause people to have unusual feelings about their physical bodies and react to their environment in ways that might make them feel disconnected from normal humans. In most cases, Therianthropes live a balanced and successful life. An individual could be a Therianthrope and also have one of these disorders with the Therianthropy being a positive part of the individual's life. If your quality of life is being negatively affected for any reason, please seek professional guidance. This information should not be used for self diagnosis.
Dissociative Disorders
Dissociative disorders involve problems with memory, identity, emotion, perception, behavior and sense of self. Dissociative symptoms can potentially disrupt every area of mental functioning. The attitude and personal preferences of a person with dissociative identity disorder may suddenly shift and then shift back. The identities happen involuntarily and are unwanted and cause distress.
There are three types of dissociative disorders:
Dissociative identity disorder
Dissociative amnesia
Depersonalization/derealization disorder

Others in this category can include but are not limited to Depression, Bipolar Disorder, Schizophrenia, and borderline personality disorder.
Clinical Lycanthropy
Clinical lycanthropy is a rare form of reverse inter- metamorphosis wherein patients believe that they are undergoing transformation or have transformed into a non-human animal. In comparison, Therianthropes do not suffer from the hallucinations or delusions of having physically transformed.

Autism Spectrum
Autism Spectrum Disorder is a neurodevelopmental disorder that impacts brain development causing most individuals to experience communication problems, difficulty with social interactions and a tendency to repeat specific patterns of behaviour. There is also a markedly restricted repertoire of activities and interests.
