Yieks! I have the same thing, sort of. I can't take my face being covered. It doesn't matter if it's just a cloth. And I have to have my hands free. If a piece of the quilt is coming over my face when I sleep, I wake up all sweaty and hysterical.... terrible. I used to dig out caves in the snow when I was a child, but while my friends was sitting in there with a candle light and drinking hot chocolate and eating cookies, I was sitting on the outside and didn't dare going in. Small rooms are bad too, but if it is a window there, I manage. I can take elevators, but unless there something special, I alway use the stairs.
Good you got yourself out
