Sounds like daymareland.
Dream: I was drawing a picture with 3 houses in it, side by side. The one on the left was teal, the one in the centre was grey-brown, and the one on the right was red. While I was the drawing, the picture sort of came to life, and all the figures were sort of moving it, like a gif image, then I got sucked into the picture. All the while, a very remixed version of "oppa gangnam style" was playing, and it went on for 6 dream hours.
Your dream - Pulled into the picture - Do you know the 80's song by A-Ha, "Take on Me"? Watch the Music Video.
Edit: (2/25/13) I had a dream this morning/last night that I was in a desert landscape at night (possibly because of my Final Project being in that background) with 3 other people or something, we climbed up a hill, saw our bus and missed it by seconds, but there was a minivan parked in the brush...And in the driver's and passenger's seats were John Lennon and Yoko Ono. Closest thing that could make me dream of that is listening to "Octopus's Garden," but still. So I get in the back with the 3 guys and I wake up.
I had another strange dream.
I woke up in my room, and it was morning, everything seemed ok, except I was saying "semi lucid" over and over again. I caught myself, but the words were still repeating in my head. I thought I finally lost it, but then I realized I just traded one sound (mini earworms) for another. In the dream, my forum story was over, but apart from that everything was ok. I was doing the stuff I normally do on weekends, although I noticed that something was slightly amiss. I was cycling in my neighbourhood when it was evening when I realised it must be the repeating words in my head. I went back and searched the forums until I found the post in Dreams where I mentioned the phrase. Then it hit me how we can be in a dream but not know. By now I was beginning to think this all a dream, then I walked into my room. On my table by the window, instead of the usual desk clutter and drawings and stuff, there was this life sized grey bionicle, as if one of my (real) bionicles suddenly grew. I just stood there, dumbfounded, but after a while I went over and touched its legs to see if it was "real". Sure enough, I actually felt it, and was thinking of some way to wake it up, when it rolled over and fell off my table. Then it got up, and I saw it was taller than me. It was saying "I shouldn't be here" and walked out of the room. I followed it down the stairs, and saw that all the colour in the house had been sucked out. Then I don't remember what happened next.
