A childhood belief about ghosts

my cousin and i both had this belief. she first told me about it when she thought it happened to her, and then i soon caught with what i thought was my own experience. she told me that sometimes when she wakes up in the morning and opens her eyes too quickly, she sees the face of a ghost. after having heard this, the next morning i saw the same thing. i must admit that the face looked more like a character out of "casper" than a real person.
