Had a dream that carried on for hours of the night, which I know because I saw the clock before and after.

I was stuck in some kind of labyrinthine like series of tunnels and rooms that I had wandered into.
Even in the dream I said out loud to myself that it felt I'd been going in circles for hours, or all night.
Unfortunately it wasn't a quiet or lonely experience, but instead I kept running into monsters.
Thankfully I seemed to be one my D&D characters that I made, a badass biker sent to another
world like Ash Williams of the Evil Dead franchise, armed with a .44 magnum.
It was more tiring in a traditional sense than it was difficult though.

It's funny how I usually lose track of time, but when asleep my internal clock is pretty accurate.
Isn't the first time I've had a dream carry on through the night, and be aware it felt that long.
The only really worrying thing I find, is that I have a tendency to not wake up until there's some
kind of conclusion in a dream with exception to something stressing me out or scaring me to
the point of waking up out of shock from the experience, guess even my subconscious hates cliff hangers.
Thankfully that's never meant me sleeping for a ridiculous amount of time, since there
tends to be montages in my dreams if something would take THAT long to experience.
