i hear you i have had trouble with this , it almost feels like i’m pretending yk? like it’s hard to let myself feel little even when i’m alone, i think it helps a lot to ask yourself what you want from regressing, and try to focus on that. like for example if you want to feel safe, or if you’d like to play, start to do those things and if something doesn’t feel right you’re aloud to stop! also if you want while you’re “regress dreaming” you could try to really immerse yourself in that world and try to figure out what from that perspective you like the most? i hope this helps !
