Players who have multiple dreamselves definitely have a unique set of advantages and difficulties. Obviously its nice to have the ability to be revived twice. I can imagine, however, it is confusing to be bounced from moon to moon.

As for drifting away from one’s dream tower- I suppose it is possible. Likely, even if one is a sleepwalker, or nearly awake. I think its unlikely for someone who has fully awakened their dreamself to float away however.
