Google says hormones, they're highest in the morning..

Or just a result of sleep cycles with healthy nerves and blood flow

Or a change in nervous system during REM sleep..

There doesn't seem to be an agreed upon answer, more just something that happens

I actually think, that only if your bladder is so full that your body wants to get more storage, so you get hard to make some more "room" for your pee. No scientific evidence, just my observation.

"An erection is all about relaxation

Although an erect penis might feel like a tensed muscle, what you're actually feeling is specialised spongy tissue designed for the sole purpose of erection (the corpus cavernosum), which needs to be relaxed to get hard."
