So I thought "single player" lucid dreaming was amazing. Now I hear about "multiplayer" dreams (more reference to my analogy). So, is this real? Do people actually share dreams and hang out with each other? People often say they meet up and have dreams together. If this is possible, how can I accomplish it? I'd really like to have a go first hand to see if it can be pulled off. And please tell me more about it, in short and simple paragraphs (if possible).

EDIT: I just found the Deep Dreaming forum but can't be bothered waiting for acceptance. I often think logically and usually would ignore the whole idea of shared dreams, but I am really excited about the prospect and it is very intriguing.
