The dark shadowy figure is usually encountered during sleep paralysis fear kicks in because u can't move or speak while this shadowy entity seems to be nearing towards you. Usually I do like u and end the session some way or another however I know enough now to use the sleep paralysis to induce a lucid dream or concentrate on inducing vibrations for separation. The best time to separate or ap is immediately upon awakening from sleep which we do several tes during the night. Namaste and gd luck!
