I've had some odd dreams lately. I thought i'd google around and see what the meaning was behind some of them...
Airplane Crash. 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 are able to carry yourself from one situation to another with confidence. To see or dream that you have a flat tire indicates that you are feeling emotionally drained and weary. Your goals are temporarily hindered and as a result, you are unable to progress any further.
