Imaginary convo

Is it normal to physically talk (like audibly say stuff) while I have an imaginary conversation with people I know irl or am I going crazy? Like I’m not keeping my imaginary convos in my head and be actually acting them out, and worse still I caught myself doing this in public (tho it’d be whispering but since my mouth would be moving it must look weird right??!!) when I’m zoning out eg taking a bus.

I’ve also “talked” to an imaginary therapist about my problems lmao and felt better afterwards, like who pays for therapy when you have imagination RIGHTTT??!!!
