Me and my friend are trying to induce lucid dreaming via a buddy system. One person goes to sleep and the other stays up and watches the other person until they see REM eye movement. then the wake buddy gives the sleeping buddy a predetermined signal like flashing a light in the sleeping buddy's eyes and saying your dreaming. If the sleeping buddy gets lucid they move their eyes in a predetermined movement to signal that they are lucid. Have any of you every heard of this or tried it?
