I had the vision of a porcupine twice. I woke up between dreams 1. There was a porcupine with a lot of long, white quills. He was quite big- the size of a small dog. I wasn't really frightened. He was sitting at the front of a door at the end of a short hallway. The door was white with a gold knob. He looked back at me and then huddled in the corner. He looked grumpy, so I never approached him. 2. Same dream, except this time the porcupine had no quills.
