A frightful or unpleasant dream, often vivid, which often awakens the dreamer out of REM sleep. Having a nightmare usually means one of the following: 1) Your subconscious mind is exploring one of your fears; 2) You are reliving a past traumatic or scary event (could even be an event in a movie); 3) You had a Toxic Dream triggered by environmental or mental/emotional stress; or 4) You have created an opportunity for negative dream experiences by compromising your responsibility for your own well-being (drinking irresponsibly, taking drugs, eating too much, giving up on yourself or your life, etc.)
