The pillow is a central feature of sleep and works its way into dreams at times. Mainly, it is as an object of protection and security. Many times, dreams of pillows include either numerous pillows or rooms that are like gigantic pillows. The former is a desire to experience the world as benevolent. The latter version may be defined as a Freudian desire to return to the womb or motherly protection.
Some people believe that certain stones or crystals can be placed under the pillow as part of the dream incubation process.
