Here's a few strange habits of mine that i think/have been told are c!dream reminiscent; feel free to include any in ur own head canons if you feel they fit ; v ;
Climbing trees!
Pesifically as high as i can get without the branches giving up on me, i used to do it just to prove i could catch myself when i was younger. Now i just like to sit in the tree tops, it makes me feel powerful for whatever reason. (was raised by cats so that might explain, same with perching on high surfaces in general)
Sleeping in odd places!
Like i physically can't fall asleep unless i am wedged between at lest two things. Always in small or hard to get to places, bonus points if i can camouflage myself. (Master of hide and go seek, i have won several times by straight up passing out in a physically implausible place)
Laying under bushes..
Strangest way i comfort myself is by finding a dark corner of the yard and just chilling in the moss. I call it corpse time, sounds mental but pretending like I'm rotting in the woods makes me feel useful somehow. (Got over my fear of bugs by doing this often when i was a kid)
Keeping a physical book on people...
(They know i do this and are okay w it btw)
Memory issues kick my ass but one way i circumvent this is by having a little notebook where i basically have a character page on all of my friends. I do this so i don't end up with a twisted perception of my favorite people, also to note down all the things they like because my love language is presenting offerings. (Started doing this after gaslighting myself one too many times, i note things down pretty clinically so i can assess people by their actions)
