I'm not sure. I've had friends that have awoken from deep sleeps having seemingly gone home, experienced any number of events that were real and have been confirmed real by their associates here, and then returned to being in Abraxas with these memories entirely in tact. For me, it's speculation based on what evidence I have.

[He is well aware that this is not especially strong evidence. Alucard just thinks it is a better-than-average guess right now.]

Do you have other theories?
