regression moments during coding breaks

i have this thing where i slip into a little space headspace during my lunch break or after coding sessions. its like stepping out of the adult world for a bit, letting go of all that stress and just being a kid again. it happens mostly when im watching cartoons or coloring in a sketchbook. but sometimes even if i dont do anything specific, im back there mentally for no reason at all. it feels good but also kinda weird. am i the only one who does this? is it normal to regress like this sometimes? should i tell my therapist about it?
