Elevator going sideways

I had a dream the other night, when I was trying to take the elevator to go up to a certain floor, hopped onto the elevator, and when I got off the elevator, I ended up on the same level as before. Instead of going up, the elevator went sideways. What's your interpretations?

 * 1) Wow I had the same dream, I don't know what it means though. I was hoping to find an answer here.
