Ego loss and development of another self.

[pickledsheep]

During a recent mushroom trip, swim contemplated the concept of ego loss. While he has yet to experience it, ego loss is something which he is looking forward to undergoing, and he has been preparing for it. Now during the comedown, SWIM had some an insight and was wondering if anyone has any input. SWIM hasn't completely grasped the concept yet and doubt he will until he has experienced, but he wonders:

When someone experiences ego loss, is it possible to begin to develop another persona before they return to their true self? And if so will this second ego stay with them when they return to their original self (in effect having multiple personalities)? Or is ego loss so overwhelming, disorienting and confusing that they have little time to begin to develop anew?
