Dream-related symbols?

[strikethrough]I've heard the hinduism symbol, or whichever it is, mentioned on the forum as having to do with dreams, but I was wwondering if there were any symbols that were specifically referential to dreaming? I'm looking for something simplistic (like a quarter note, or the 45RPM spider, or a pair of headphones can symbolize music, preferably nothing that is inherently complex, or anything with a lot of detail like the australian paintings with all the hands.)
Can anyone think of any symbols that would be specifically about dreaming? If so, please post images, descriptions, or titles here.[/strikethrough]

I just made a separate thread with more information over in Dream Control, and it sdoesn;t seem that I can delete this thread, so could a moderator or administrator please delete it for me?
