Is Cryo-Sleep real and/or possible and if so, how does it work.
Movies like Interstellar and many other fantastic films about space all seem to have a common piece of technology, Cryo-Sleep. I have never heard of anything similar happening in real life but I have always been curious as to how it could work or if it truly exists.

No, it is a SciFi trope invented to deal with the fact that space is vast and the speed of light isn't as fudgeable as authors would like.
There are all kinds of problems with freezing someone and then thawing them out. A lot of the body is water and water is denser than ice, so when frozen it expands causing cell damage. Anyway, SciFi waves the magic hand of science over details like that unless it is helpful to the plot somehow. As Arthur C. Clarke famously said, "Any sufficiently advanced technology is indistinguishable from magic.", so how are we to know what magic/technology is permitted in fiction.
