THE DREAM I was riding a bike and my girlfriend was also on a bike. I ended up having a bad accident on my bike.

THE REALITY The dreamer and his ex had split up. The dreamer had probably come out much worse than his ex who seemed to be coping.

THE INTERPRETATION Its a common thing to want to be doing better than your ex girlfriend. You want to show them how well you are doing and you want them to see you with an attractive member of the opposite sex. If we have bitter feelings towards a break up then perhaps you will even enjoy seeing an ex fail. Your thoughts will be full of these types of feelings. Whenever a relationship ends then one person generally comes out of it worse than the other. In the dream the dreamer clearly is seen having an accident and in difficulties.
