I picked the wrong post to read after a joint.

Uh?

Use the entrance to the Astral Sea nearer the parking garage, over by the Cheesecake Singularity. Way nicer astral neighborhood, though everything costs a bit more mana.

Maybe try learning some latin?

First find (or fabricate) astral cassus belli, then hire astral mercenaries

What's with initiates and slip dwellers? As your instructor has doubtlessly told you, they're fine as long as they aren't speaking Enochian. Don't worry about Latin, Aramaic, or any of the Proto languages - those sound scary, but they aren't a big deal.

If you do hear Enochian, immediately ward up (you should have already, but if you're asking about Latin, you need a reminder), and return to your mortal form. Report the infested slip gate to your ranking practitioner.

OP is talking about an esoteric pseudoscience named astral projection.

I don’t know if I want to believe in it or not, but I’ve never heard about missions and closing portals.

I have no idea, but commenting because I'd like these answers too. Hope someone can help!

Which religion is this?

I once tried lucid dreaming, but couldn't fly into space... Bounced off the dome and woke up. :/

Dude. Are you sure you have your mat aligned properly? What kind of compass have you used? You need to align your mat perfectly due North. Remember: the magnetic north. Not the "true north", which would misalign you on the magnetic lye-lines causing all kinds of halucinations. Don't use your phone but a real compass and make sure there is no interference from metal objects.

Get your belly full, reverse genocide purple worms, wield a rubber duck, and leave Team Ant alone. And remember: you aren't there to fight, you just need to offer that bloody amulet on the right altar.

And what do you guys do about the faces in the slip gates that speak in latin?

Just don't #chat with them. The most that they'll say is "quid esse credis, Bellum?" anyway.

Incense over the work station, speakers playing the chanty, recite the versus. When you see the slip gates Remember "My armor is contempt. My shield is disgust. My sword is hatred". A mind unguarded is like a fortress with the drawbridge down. Normally I get kicked out by the locals when they go for the jump scare and the punch their face. Pretty funny.

Try to fob it off to Jason Asano. Because no way am I skilled enough at that and Jason and the Builder already have beef with each other.
