>but I don't want to invite anyone yet because I don't know how lucid and stable my place is for others or if they can even join at all
Here's something you can use to practice. My lyran ship up there has an astral section which is open for visitors. You can astral travel there and you'll be let in if you're allowed to (the A.I. will determine). Just focus on the spiral of this image for about 20 seconds, then proceed as normal with your astral travel session.
The lobby has different tables out of which some are open and others are reserved for VIPs like the techno vampires from Black Hell group. You are free to approach other visitors and join them at their table if they give permission. There's also a bar where you can order food and drink (energy for its replication will be taken from your natural qi flow which is connected to the ship during your stay so everything is "free").
