Should be in food and health really but they sound like impotence dreams. I frequently used to have dreams where I was cha sed by something or other and the gun I would find wouldn't work or the lock on the door burst or the car wouldn't start etc. Traditionally this relates to impotence in a situation rather than your dick. If your not aware of them I can post some dream control tricks. I found them helpful and they make bad dreams actually kind of fun and exciting.
