Excuse me for commenting on vent art, but I love all the variety in the types of snakes, even without colors or patterns.
Just off the bat I can recognize a hognose, a ball python, a larger python (burm/blood/retic), a horned viper, one of those fancy tree boids that I keep getting mixed up (emerald tree boa? green tree python? idk), and a couple various colubrids.
Seeing so much art of snakes as uniform noodles with oval heads gets old and this is just really nice.

Hee! I'm so glad you recognized the blood python! Yeah I love snakes so much ;w; they all have such cute distinct faces. The snakes I drew are

Carpet python, two ball pythons, blood python, a hognose snake, cerastes cerastes, and two texas rat snakes ^^

Ah, the carpet python is the one that got me. To be fair though, green tree pythons and carpet pythons are the same genus and do have very similar shaped heads.

to also be fair, I drew them all without reference so they're probably not entirely accurate anyways XD;

Man, that would scare the hell outta me, though.

I thought the title was 'I had a nightmare' at first, heh! As though you had a nightmare where you couldn't stop throwing up snakes and/or they kept erupting/slithering out of your mouth.

Anyway, this is an ability I would appreciate too, kinda. In theory, anyway. >__>

Very cool picture, and I'm with Crou, I like the variety and attention to snake-detail you put in there. But, of course you would! :D

I thought this was one of those "Misheard lyrics" art pieces... ... ... but nope. Someone wants to throwup snakes. ... aaaaaaalllright...
