Two nights ago (21st of July, 9:30pm London time) I was lying in bed looking out the window in a westward direction when I saw something really strange. Just above the horizon I saw something about the size and shape of the moon in mid-cycle, a crescent. It was of a red tinge. I watched it for 30 seconds and it slowly waned and then disappeared. It was really bizarre, I am on malaria pills which CAN cause hallucinations but I've had no other problems with them as of yet.
