Numbness — most often the cause of these dreams is bad posture. If not so simple - perhaps you are cut off from their own feelings and put down their fears.
To dream that you feel numbness, indicates that you are letting fear take over and run your life. You are afraid of taking risks or chances. You fear failure.
To dream that you feel a numbness creeping over you, in your dreams, is a sign of illness, and disquieting conditions.
