Oh shit, I just remembered. I was dead afraid of sleeping in foreign houses, like a new friend or a relative.
I wouldn't be used to the noises at night like the AC oor furnace or if the house creaked. The bed would feel weird. If they had pets, they would move around at night and I'd either cry or hide. I'd usually hide under the covers and try and go to sleep as fast as I could. Then, of couse, I couldn't :crash:
The dark. My mind ran rampant with strange thoughts of some robber sneaking into our house, and it kept me up at night for a long time. For a while I went through a phase where I would have to cover my throat when sleeping because I was afraid of someone slitting it. Weird...
