A British expression used to indicate that something has gone horribly wrong with a person's plans, most commonly in the phrase "It's all gone pear shaped."

1. The occasion of having a nightmare and waking up from it, only to soon discover that you didn't really wake up at all. And repeat.
Best if each pseudo-waking involves conversing with someone sleeping beside you.

2. (in cinema) When a film has an eerie moment involving a nightmare which a character is unable to wake up from. The character will continuously wake up each time by gasping and sitting up in bed. Usually a cheap attempt at something psychological or "artistic", with vague dialogue from the character/s feigning profoundness.
Also usually followed up by an interesting experiment with camera techniques, and some vague imagery hinting at existentialism. Always done with suspenseful music.
