How interesting that this comes up as I'm having a discussion about space time fuckery irl.

It's been happening with increasing frequency in the last years and yes, in the last few weeks I've done so many things that I definitely did before in some other timeline.

As for dreams, as a child I once had a dream that I along with one other was able to access a backdoor fluidic realm containing liquid mirrors leading to all my previous dreams, and I was able to enter and exit them. The nearest approximation would be the doors Neo took on the way to the architect that only the Key maker could open, but we're talking a decade prior to that movie.

Time has never looked the same since.
