Creatures

Why is this happening?
I see things no one else see
For example, I see white figures
Hopping and jumping in my trees
They are neither dead nor alive
Just mere shadows in the light
They seem very comfortable with me
They give everyone else a fright
They seem to want to talk to me
But their speech I cannot hear
They talk in mumbled words
They all fill me with fear
One of the shadows I do understand
But I don't like what they say
They say I'm gonna die soon
And they say it in such a happy way
Everynight I watch them from a far
But one day they scared me
I blinked for a split second
Then they were right in front of me
One of them had a knife
The others had boards
They kept coming closer
And I knew I was done for
The freaky shadows tore me apart
And I didn't know why
I looked at myself as I left my body
And all I could do was cry
