how tf did i get overstimulated by my own thoughts??

so i have ADHD and last night, i was trying to go to bed and there were genuinely like 15 things going on in my mind, most of them annoying. like i remember one of them was this like harsh high pitched like buzzing but it’s not like yellow or white buzzing, it was like orange. it gave off an orange vibe. but aside from that, there were like 15 sounds and videos and memes and random things all that suddenly appeared in my head and it genuinely pissed me off and idek what constitutes overstimulation bc i wasn’t like crying but was very overwhelmed and annoyed.

never had this happen before, usually it’s just a couple background noises in my mind. any of you experienced this?
