My dream caused me to wet the bed - why?

Question

Last night I was dreaming that I walked down the hall and into the bathroom.I stood by the toilet urinating.I felt like I was going for a long time.Suddenly I woke up & realised I didn't go to the bathroom but urinated in my sleep!! I was SO embarrassed.I had to wake my girlfriend up to change the sheets.Luckily she didn't make a big deal of it.Why did I dream this & why did it feel so realistic?

Answer 1

Had you by any chance been drinking earlier?

Answer 2

Actually, it's the other way round.

For whatever reason you had a nocturnal mishap, your body recognized the sensation of peeing and it came up with a mental image to match. Thus your peeing caused the dream, not the other way around.

The human body mind is well known for doing this. For example, if you are asleep and it is really windy outside you may have a dream with wind in it too, or you somebody might start shaking your bed to try and wake you up, and you have a dream that you're in an earthquake.

Answer 3

The dream was probably your subconscious mind letting you know you had to urinate.  As to why it felt realistic... well you did relieve yourself in the bed.  It doesn't get more realistic than actually doing it.
