Because they usually sleep more, pensioners have a much greater chance to enjoy the surrealist landscape that is their dreams.
Dreams can be both frightening and entertaining, but the symbols they use are relatively easy to interpret.
Trying to run but not moving. You are failing to face up to an issue which you should be addressing.
Swimming. You have a strong desire to return to the womb.
Being hit with a banana. You have developed an irrational fear of fruit.
Being in a tumble-dryer. You have fallen asleep in a tumble-dryer.
Standing under a waterfall. You should wake up and go to the loo.
Having sex. You have fallen asleep during sex.
