Something i recently realized about myself is when im possibly about to enter an episode, i experience some really significant sensory disturbances? 
I think when im nearing an episode of any kind i get really really sensitive to sounds and im super susceptible to auditory overstimulation. Lots of sounds happening at once like people talking over a video or repetitive/loud sounds get incredibly frustrating and agitating really quickly.

Things touching me that i don't appreciate suddenly make me a lot more agitated, like a sweater that i like suddenly being too itchy. 

Colors also become a lot less vibrant when im heading toward a low. Places with a lot of people and/or movement make my mood difficult to manage. 

Does this happen to anyone else? Does it sound familiar or at least faintly similar to anyone else's experience?
