Yes, I have become very sensitive to noises and light over the years. I also have a low stress threshold. Someone mentioned airports? They are major triggers for me.

I have a difficult time falling asleep unless my room is very dark and very quiet. The room's temperature can also be a factor.

The only sounds I can fall asleep to are ones on my sound machine (i.e. fireplace burning, rainfall, brook, and similar) or those particular sounds actually happening in real life.
