can you ever be tired in an LD? a bit drowsy (you are sleeping, after all) or maybe just running out of breath after sprinting across the pacific ocean?
has anyone ever been tired? do you think its possible?
You can be tired if you want to 
But who wants to be tired 
I have been totally groggy and super tired in lucid dreams. So much that I felt the need to rest even though it doesn’t even help. It wasn’t from exhaustion, it was, for no aparent reason. I guess I was just mentally tired.
Recently I´ve had a couple ld´s where I felt so tired I could barely move. It doens´t happen that often and I have no idea where it comes from.
ive never been sleepy in a dream, strange cuz im really sleepy once i wake up
The closest i’ve felt to being tired in an LD is one dream I had where right after i became lucid, i could feel my self leaving the dream world and waking up. But in the dream, it felt like i was falling asleep, but i knew i was actually waking up.
Its kind of hard to explain… like waking up from a dream for me, sometimes feels like falling asleep in that dream.
I’ve also found trying to go to sleep in your dream is a good way to wake up from it, but it can also cause false awakenings. Which can be even better, if you just wanted to get out of the dream you were just in, but not necessarily wake up.
