I can almost always lucid dream, but Iβve never been able to turn into not-me. No issues with flying (except the damn power lines in the way), sexy-time-on-demand, using doorways as portals to wherever I want to go, etc, but if I try to become not-me, I wake up. Canβt say Iβve ever tried to become a cow, though.
The guy who was turned into a cow found out that day all his coworkers had secretly been furries the whole time.
