Which nightmare would frighten you most?
Waking up to find that neither your friends nor your family have any idea who you are.
Being forced to speak in such a silly voice that hardly anyone can understand you, and everyone laughs at you
Standing on top of something very high and realizing suddenly that there are no hand- or footholds, nor any barrier to stop you falling
An eye at the keyhole of the dark, windowless room in which you are locked
