MoE104-105.
The operative sentence is "When this effect is used, everyone and everything is reset to the state they were in at when the subject's turn began." and "The only exception to this is that any power points spent to manifest forced dream are not recovered."
This seems to mean that the target and all other creates will not remember the use of the restart, except to count the loss of PP. This seems to mean that unless the manifestor is willing to A) write out a list of exactly what actions are going to be taken [perhaps to the point there is no real room for improvisation] and B) stick to that list without deviation [because on the same try, the same choices would be made], this power is not useful...
Unless the player metagames worse than taking the DM's notes and monster entries. After all with trial and error while metagaming to allow a PC to remember these things, both of those are achievable.
