I actually can have Ludd dreams too.
However its nt as cracked up as it seems.
For everyone else: You dont get as much sleep with it.
For X: I think you can only get to REM Sleep 2 with it. When haveing a Ludd dream, you're still baaaaaaarely conscience. It's like you're daydreaming but in a "sleep like" stasis.
Also, you can also feel time pass by alot slower, feeling every hour that goes by. Then agaim...........probably every two hours. Yeah it may go by slowly............but not too slowly.
Of couse you're too busy dreaming to care. Eventually, sleep takes hold and you fall asleep after a long while.
I used to have them all the time, but I wanted to get sleep more so I started just going to sleep. Found out that more than 40% of the time, I never had any dreams.
That was fine too. Since I usually spend most of my days with my head in the clouds anyways....
