It’s 1.38AM and i am tired!
For extra info, i’m working on a macbook pro with 16gb of ram memory. I know laptops aren’t ideal for blender, let alone such rendering but it’s all i got.
Well, if it crashes, it crashes. I don’t think you depriving yourself from sleep is going to make any difference.
Other than some odd crash happening it should be fine and the render should still be there come morning.

You can leave a PC running all night if needed, but first you will have to turn off the OS’ sleep/hibernate feature (which will pause your render until you wake up).
That applies to desktops at least, laptops have the added variable of the battery and whether heat flow would be optimal if the CPU was at full blast while the lid is down.

If you are rendering an animation, it’s best to render each frame as a separate image, then combine them afterwards. This way, if something bad happens you won’t lose the entire thing and you’ll only need to render the missing bits.

YES! you should definatly sleep (or do something that doesnt involve staring at your computer screen) while your computer is doing a long render. Turn off any sleep mode (my laptop is set so it only sleeps if not plugged in) and sleep during long renders.
Is it animation or a single image?
For a single image, if you’re not doing compositing, I’d render it in sections so you can be sure each section will render before your system overheats and crashes. You can combine the sections into a single image later.
