So I’ve got this problem with my eyes. They seem have the urge to try to open themselves. I try to relax thembut as soon as I’ve lied down for like 5 seconds they start opening themselves… Then I try to close them steadily but the procedure repeats itself. Is this okay/is there a way to keep them shut and relax them? This is getting on my nerves!! 
Yes, try reverse blinking. Start with your eyes closed. Then, open then and rapidly close them again (just like blinking, as the name implies). After a while you’ll find that this will tire your eyes out and it’ll be much easier to keep them shut. Good luck!
Rhewin’s tip helped me every time i had this issue 
. I also find meditating for 10 min helps to relax eyelids and body overall.
