Age regression, as we refer to it within the community, is not a mental illness, impairment, or disorder. That being said, you should always feel in control and aware of yourself. It shouldn’t ever feel like you’ve truly forgotten how to function, maintain your own levels of safety, or perform important tasks that may unexpectedly come up in the moment. You shouldn’t feel like you’re “watching” yourself do something, as if you’re only a passenger in your body.
The term alter implies that a different consciousness has taken over and that you
aren’t in control of your body’s decisions. If that
is actually happening then that is not
littlespace or regression. That would be a psychological condition that only licensed therapist can, and should, treat. You may simply be misusing the term alter, in which you can easily stop doing so and use more appropriate wording to explain those moments.
It’s absolutely okay if you felt so
carefree, relaxed, and safe enough to express yourself through regression that you felt very youthful again. In the end, moments of deeper regression is just the physical manifestation of self-expression, and every person needs to have those times in their lives. Endorphins can absolutely play a role in feeling very positive when you feel that sort of freedom of expression you’ve kept bottled up. I hope that you continue to feel this sort of elation when you get these opportunities to express through regression.
