It had my head in a vice-like grip and was "reading" me.

It wasn't SEEN,it was heard.Read the whole story,as it is weird.
The head of my bed is up against my bedroom window.  I was asleep,when i woke up to noises like a computer beeping directly behind my head-outside of the screen (the window was open).  More like spaceship's computer beeping noises, like on old TV shows.  I tried to turn my head to see what it was,but i was unable to move my head at all.It was like it was in a vice.I could sense that my brain was being "read",and i mean that i was CERTAIN!  I thought maybe i was dreaming,but couldn't shake it,and started to get scared.I heard my daughter in the kitchen(right next to my room)and so i tried to yell for her,but i wasn't making any noise!So I tried,and with ALL of my might,to scream her name.This time it worked,and she came running.I still couldn't move,by the way.She opened the door and said"what's wrong"? So i yelled(since i couldn't move still,and the noise continued)"The light!Turn on the light"!  As soon as she did,the noise stopped and i could move.
As creepy as this was,I figured it was a dream.But my daughter insisted that I sleep on the couch,and I was happy to comply!  Anyway,I pretty much dismissed this,but the next morning when we went out onto the porch,we looked at the huge tree behind my window.I have a second floor apartment,and this tree is so big and heavy with leaves that it hangs over the porch.Until THIS morning--most of the branches and some of the leaves were still there,but all of the bark had been stripped off the tree!!OVERNIGHT!! And the tree is in the exact spot where the noise came from!  By the next day,the tree was dead.This was a healthy,green and leafy tree! If it weren't for the tree,even though i was sure that i was NOT dreaming,I'd still believe i was asleep.But what about the tree?
