From what I understand, yes, you could definetly be out-of-body and then lose the memory download that early in the experience...or OB right after you "fall asleep"...
fides quaerens intellectum
when trying to project, and very close to the exit, has our consciousness been projected into the double? i'm wondering if i've had projectoins and just don't recall them. i've made numerous attempts and have come very close. i've also had a few spontaneous projections so i know what it feels like when i do get out. i've had many attempts where i came very close to the exit but just ended up falling asleep because it didnt work. i'm wondering where the line is that you have to cross that you would start to lose shadow memories.
