Reality contains the illogical quantum realm. Also some computerized randomizers are not truly random. Then there is the famous consciousness experiment that uses random generators called the EGG.
If you don't know about it prepare to question your belief system.

Good for you Mr. Red for knowing what a wave collapse is. That the wave collapse goes back to its original variability is technically going back in time. The reason why the mega universe doesn't have this ability is that there are way too many particle waves (atoms) involved to act in concert together to reverse its time direction. On a quantum scale with one variable, it is easy and natural for time to be reversed. By the way dark matter may be particles that are going back in time making them invisible to us.
