Sleep?

I haven't had a good night's sleep in the last two weeks (this is a regular thing for me--cycles of sleeplessness). I'm starting to wonder--is my insomnia due to the fact that there are issues and conflicts left unresolved, or am I afraid of that I will be haunted by dreams  the next day...or both?

Sometimes I wish some of my infatuations, problems, and thoughts would just vanish...why can't I just count sheep and dream little dreams like everyone else?Why do my dreams have to be representative and contemplative of issues in my life? Life is already so complicated when I wake up...
