While laying down trying to sleep I feel this feeling in my head as if I were upside down anyway to help sleep? I feel shaky a bit to. Also feel dizzy

Dizzy and shakey. makes it tough to sleep and is I'm sure alarming to you. You should have that looked into if it does not resolve on its own within a few hours. May have a problem with one of the balance organs in the inner ear. I don't have enough information to know exactly what the problem is based upon what information you have given. The most common cause of dizziness in a teen is side effects from medication.
