When you do something in your dream, will there be a mess in the morning?

So here's what I mean: when I poop, pee fart burp and jizz in a LD, will it happen in real life?

Also will you talk / groan in real life while talking in a LD?

EDIT: I just read that back to myself. Made me giggle :)

Relatively speaking, Lucid Dreams work in the same way as regular dreams. So unless you already suffer from said problems, you should be fine :)

From extensive experience, no. Although it might be different if you're a young teenager who doesn't 'bate as much as he should. ...lol

When I was 8, I went to the washroom in a dream and ended up waking up, having actually done it. But that's the only incident I've ever had.

I would assume if you had enough intent in a lucid dream, that it is possible that your body would mimic the action. As a side note, many people ejaculate after doing so in lucid and non-lucid dreams, so there is some proof.

Yes, it can happen. Most of the time you don't need to worry about it, but if you really need to go, it could get messy.

I speak from experience. Wasn't catastrophic, but I took a nice long pee in my dream, and only peed a tiny little bit in RL.

I don't think i would ever spend one of my LDs going around pooping on stuff.
Think of a regular dream. Do you pee your bed normally in a regular dream?

I think mattbrox's primary concern is quite clear; given the list, there's only one thing that most of us gentlemen would be involved in as the result of a lucid dream.

But in theory no--however, if you have some how figured out that you have dreams outside of the REM stage, and can become lucid in those dreams, there's a much higher chance of sleep walking, sleep pooping, or as I once did, sleep-showering.
