I have that too. Recently it's a song from a stupid tv commercial. The one about free credit report commercial where that guy is dressed like a pirate. I hate that. LOL
Now, if I could wake up with Led Zeppelin, AC/DC, Aerosmith, Lynyrd Skynyrd, The Eagles, or anything classic 70's, in my head....I'd be happy as a lark!
I usually dream in color. Once in a while I'll have a B&W dream. But that's usually when I'm not 'participating' in the dream...(just a witness to it).... and it has something to do with me thinking about what I should've done in a particular situation. By being in B&W, it's like my dream is giving me a view of an alternate solution, outcome, or possibility about something.
The beauty part of weird dreams, is that people don't think you're 'nuts' when you tell them. Because they're told as, and accepted as, 'just' a dream or nightmare.
I spent a whole night singing that creditreport.com song. Everytime I opened my mouth, I'd be told to shut up, lol. That is until I got my dad singing it. It's highly addictive, I tell you. I also sing the one about the used car he gets... "F R E E that spells free, credit report dot com baybeee"
I never thought about b&w dreams that way...but I usually participate in all my dreams. I'm usually the focus. Normally, people don't judge my dreams...unless they're sexual. Then people look at me like I'm crazy, lol. But I usually have really cool dreams, so they're actually entertaining.
