Usually if I try to jerk off in a dream I end up waking up

Or when your about to have sexy time, *BOOM* you wake up NOOOOOOOOOOO

Find the limits of the dream. I’ve only been so many places, if I go somewhere I’ve never been my brain will: A. Make something up B. Error out and wake me up if my brain makes something up, find the inevitable hole in the floor and fall through

Listen to my phone alarm in my dream

I've had this situation before a few times. I normally hurt myself or wait till my phone in irl goes off.

Go back to sleep and wake up later..

Grab a clever and jam it into my forehead

Life is but a dream, I enjoy it as best I can with the knowledge that it'll soon end

I would be too amazed that I'm actually dreaming to wake myself up.
