I have trouble sleeping at night. It feels like potential ghosts messing with my sleep. Tips?

Some ideas... ...To help with sleep involve improved sleep hygiene. To achieve this, try to go sleep and wake up at the same time every day (including weekends), avoid things that can significantly alter your sleep patterns (alchohol, drugs, caffeine), exercise at least 4 hours before bedtime, and keep stimulating things (tv, computer, cell phone, video games) out of the bedroom. Don't worry about ghosts!
