Age regression occurs when a person reverts to a younger state of mind. They may regress a few years back from their current age or, in some cases, return to a child-like or infant-like state.
Regression is a normal and temporary condition for children, and it can be a coping mechanism for stress and untreated trauma in adults. Examples of regressive behaviors include baby talk, thumb-sucking, and temper tantrums. These behaviors can be voluntary or involuntary. -verywellhealth
Age regression occurs when someone reverts to a younger state of mind. This retreat may be only a few years younger than the person’s physical age. It could also be much younger, into early childhood or even infancy.
People who practice age regression may begin showing juvenile behaviors like thumb-sucking or whining. Others may refuse to engage in adult conversations and handle issues they’re facing. -healthline
age dreaming is an umbrella term for those who’s headspace does not fit beneath the age regression umbrella. it is a diverse, individualistic experience, which is different for each person. the headspace is usually controlled by the individual and voluntary.
it may encompass those who go into a child-like headspace for fun, those who act/behave like a child nonsexually, those who’s headspace is both “child” and “adult” (aka not fully ‘regressed’), those who consider themselves to be a child and partake in a lifestyle of reliving childhood, and those who just enjoy the aesthetics and comfort of childish things. in all cases, age dreaming is a nonsexual act, not related to kink or nsfw activities. -agedre tumblr
Pet Regression is the animal counterpart of age regression. Instead of regressing to a younger age, pet(re) reverts to the mindset of an animal, though both age regression and pet regression may co-occur and are not exclusive to each other. The animal mindset can range from household pets, to wildlife, to mythical creatures, and more.
When regressed/regressing as an animal, pet regressors may take on the behavioral patterns similar to the animal they are in the headspace of. The dreamer counterpart, where regressors do not often fully slip into an animalistic mindset, is known as pet dreaming.-pluralpedia
