Many times when I sleep I kinda like to imagine a scene happening. Although imagery will usually be weak, what really interests me is that all the sound becomes a high pitched noise fast. The imagination usually takes over by this time and I can't quiet stop it from taking course. And each sound keeps getting into this high pitched whining noise. Usually it kinda makes me jump. There are a few places to post it, but this feels the best place for this sort of post. Anyone get this sort of thing? Anyone know if it's HH?
