feeling snarky and irritable?

does anyone else feel really irritable sometimes when someone perceives them? this goes especially for my parents and i notice it most when im home from college. sometimes i just do NOT want to be perceived and i want to exist in my own low sensory space, and if someone comes in or talks to me i get very snarky unintentionally.

sometimes ill even feel like im floating when theres too many people or its too loud or the lights are too bright.

this always happens after i come home from like the mall or some highly populated place, i just do not want to be perceived the rest of the day. is this normal for anyone else? i haven’t been diagnosed but in the past month i’ve discovered that i am most definitely a high functioning autistic. i’m still trying to learn about myself :)
