Twin birds
I was outside. There was an open grassy area surrounded on two or three sides by thick red brick walls. There was one other person with me. On the grass there were birds and he ran up to catch one and found out it was two stuck together. Small black birds whose tails were fused and their heads were attached by a narrow strand of skin and they couldn't fly and escape like all the rest. There was a very large, motionless hair covered beast on the grass and a ladder up against it. I climbed the ladder and noticed a small creature with a face that had a human intelligence and mischief hiding in the deep dark fur of the beast. I climbed higher trying to see or find it, but it was too quick and I couldn't keep track of it for very long.
