Im confused on whether or not i can do a WILD when i go to bed at night or if the whole 5-6 hours of sleep before you do it is nesescary. In all of the tutorials it says you should have 5-6 hours before you do this. Why is this? And why cant you just do it right when you fall asleep?

It would be awsome if somone responded soon because im about to go to bed and i want to be able to try it again tonight haha
