If you wake up in the middle of a sleep cycle, but go back to sleep imediately, does it restart or resume?

Question

Does it matter what stage in the cycle you wake up in. Also is it possible to do 6 quick consecutive 20 min sleep cycles instead equally spreading it between 24 hours (for polyphasic sleeping) since I heard it was the amount of total rem sleep cycles completed that mattered, not total time, so I theorized that rem sleep cycles should be cumulative since monphasic sleepers go through 4 -6 cycles every night consecutively.

Answer 1

wtf

I don't know, but I would also like to!
