Strange thing happen at 3AM, all of a sudden I woke up and I couldn’t go back to sleep. Seems like I heard some high bass sounds around the around the house, I walk around the house look out side the window, the moon was bright and can see things clearly outside. Then I notice the trees and tall grass were moving then came to know it was just the wind. I thought some neighbor car playing high bass music, which is next to impossible around here, it’s a pretty good neighborhood :). I came back to sleep lol. My recommendation if you can’t sleep after waking up middle of the night, well you could try counting sheep, listen to opera music, turn on tv with sleep mode 60mins or so but don’t watch, lie down up side down, don’t think of business or anything depressing. Think of vacation paradise or fantasy land, or happiness in the past with friends and families and so on 🙂
