Well i had a brief WBTB/DILD last night and i was focused on flying, well i was gunna get a running start but it seemed like i was only running in place really slow, like the land was sliding back when i pushed forward. after that i bent my knees a bit about to push off with alot of force but is soon as i tried it felt like my legs just became weak, like i barely pushed off at all, i only got like a 10ft jump, then i woke up. Why would this happen? This is the first time i ever had a problem with my legs in any dream
