The Atheist's Nightmare 

The idea proposed by that asshat Ray Comfort that the banana proves God's existence.

"Behold! The Atheist's Nightmare! I have a banana! It proves God exists!"

"Behold! The Theist's Nightmare! I have a pineapple! It proves God doesn't exist!"

reverse nightmare 

When the nightmare is actually waking up to reality.

Reverse nightmares are usually followed by the chest-crushing realization that it was all just a dream and the dreamer must readjust, yet again, to the grim reality of waking life.

The most common of these events usually deal with someone's permanent absence (whether through death or break-up).

''I was dreaming mom was still alive and everything had been a huge mix-up.''
''God, I hate those kinds of reverse nightmares... they just make it that much harder to get over the pain.''

Nightmare Flipping 

The mixing of the following two drugs: Diphenhydramine (Antihistamine commonly known of as Benadryl, and when taken in high dosages can be a powerful deliriant) and MDMA, the drug commonly known as Ecstasy. Is known to create extremely interesting effects on the mind. Sometimes can be unnerving.

Don't recommend trying this unless you are interested in the experience. First try DPH (Diphenhydramine - Note, this isn't a fun drug to most) and MDMA (Ecstasy) separately if you haven't already.

Psychonaut 1: Hey man, have you tried Nightmare Flipping?
Psychonaut 2: Nah man what combo is that?
Psychonaut 1: It's a mixture of that deliriant Diphenhydramine and of course, Ecstasy.
Psychonaut 2: Woah, I never thought of trying that, sounds interesting!
