Within the past two weeks I have been writing poetry in the notes section on my iPhone in my sleep. I normally do write poetry, but some of what I am waking up to does not sound like me at all. I also do not remember writing in my sleep and only realize it when I look back at my notes and see a new poem. About 3 months ago I was put on a new sleeping medication- Seroquel. I'm not sure why this is happening and it's kind of freaking me out. If anyone knows anything regarding this and can let me know anything at all that would be great.
Here are a few i've written in my sleep:

Little girl little girl
Didn't your mom say
Stay in and play?

and another:

I have the eyes of acid
Tripping over the realm of insanity
And Conjuring myself to the Devil

please help
