No, but I had some serious panic attacks between the age of 30 and 50 and I didn't tell anyone. For some reason, they go away after 50. For me, ninety-nine percent of the time panic attacks happened at night. Some times I would quietly slip out of bed and repeatedly throw cold water on my face inbetween pacing inside the house. Other times I would walk outside usually in the wee hours (3am) and when it was cold out. I don't know what was worst, having the panic attack or being discovered that I was having a panic attack LoL. What kind of delusions were you experiencing? What were the visuals? Were you asleep or awake?
I learn about Aphantasia while doing random online searches for some project I was working, that was around 2014, I was 55 at the time and it stunned me especially after I read about the "counting sheep" example. That was me, I never got the reference just count sheep and you will fall asleep; I thought how does anyone do that? After reading the article I was overwhelmed with a profound sadness about my life which always seems to go sideways and how difficult it is for me to connect socially. I am still affected by that sadness/weirdness to this day.
