Can some one explain this to me?

ok, im 13 and ever since i was a small child, i get some-what scared/freaked out by things that swing without a controlled axis. This also happens to me when i turn the cieling fan off and it swings around in a slow motion way. A reletavly similiar effect happens when i listen to extremely loud music. I have noticed these things only seem to bother me in the evening. It sometimes gets so bad, i wish i could be in my own world with only me in it where there are no swings, wind chimes, pendulums, cieling fans etc. i need help. please tell me everything you know on this subject.
