Guys, What does it mean when a guy texts you at 2am?

We are both Christians so I think sex is out of the question but one of my guy friends that I have a crush on and I will send each other memes and talk throughout the week, lately he has been sending me memes from either 12-2 am, I asked him why and he says he can't sleep and doesn't know why? what is up?
