As far as my reasoning goes they can last a full Rem period. This period get longer the longer you sleep.
Agreed. When I WBTB and WILD they usually last around 20 minutes, but im sure I can get it longer if I wanted but I tend to get excited. Ive also heard of people saying they spent what felt like 3 or more days in a LD by slowing down dreamtime or something to that effect.
