One pretty weird dream I had many years ago was that a plane crashed into my school's playground, then skeletons got out and started driving jeeps into the wreckage. I've had weirder, but I can't remember them. That one sticks in my mind because it was a recurring dream.
I had a look at the Dream Moods website and it said:
'To dream that a plane crashes signifies that you have set overly high and unrealistic goals for yourself. You are in danger of having those goals come crashing down. Alternatively, the crashing airplane represents your lack of confidence, self-defeating attitude and self-doubt. You do not believe in your own ability to achieve those goals. Loss of power and uncertainty in achieving your goals are also signified.'
'To see a skeleton in your dream represents something that is not fully developed. You may still in be the planning stages of some situation or project. Alternatively, a skeleton symbolizes death, transformation, or changes. You need to get to the bottom of some matter. The skeleton may also be a metaphor for "skeletons in your closet." Do you have something to hide?'
