Do sleep cycles get interrupted, or reset?

I had trouble wording this. Bear with me.

I know I go through several sleep cycles every night. Last night, I woke up thirsty and went to get myself a drink. I was pondering whether, once back in bed, my brain would jump in where it left off.

I’d appreciate any links or information on this. Because I’m a very deep sleeper, I’m aiming to wake up between sleep cycles. Will my need for water mess this up?
