I occasionally dream that I'm being hit with something, like someone swung a bat at my head. I always wake up when it makes impact, and it's like someone just sent a few volts running through my body...
But yeah I dream about weed constantly. I obsess about growing as well. Every night before I fall asleep, the image of a full grown cola in my closet comes to mind... *flash*... a full jar of homegrown, all to myself...
Its a good thought.
