A flying head

After all those notes I took I'm beginning to wonder, what the hell brain? I know that most of dreams have absolutely no meaning and only sometimes relate to the real events, but why so abstract?

This time in my dream I saw a big flying head, telling about the need to do "it". It never said exactly what the "it" was, but it was clear there was an importance and the need of the "it" to be done. After each sentence it spun around in place. 

I woke up here and went to the bathroom. I had another dream, but it was nothing special. Just some people I know talking about cucumbers. And no, I don't know why.
