Though, after singularity, you will be able to physically revisit any time, at any place, at your will. All it takes is belief that you can do so.
Sorry Dank, that's your psychosis talking.
The one limitation about closing your eyes and
imagining yourself in different times is that it is
imagination. (i.e. Your body can't come with you).

But you keep dreaming - nothing wrong with that.
