Pie in the sky.

I'm no stranger to seeing things like this after a few pints of Green Hop Ale, as taking a powerful soporific while trying to stay awake can have a mildly hallucinogenic effect.
Though I feel I should point out that I'd not actually drunk any of the stuff when I snapped this outside of The Red Lion in Ramsgate yesterday evening, and if it was indeed a hallucination, I'm led to understand that they're normally buggers to take pictures of!

Hmmmmm.
