Also you can use sigils and seals electronically, if it’s safe to view them on your personal device and delete them when you’re done.
For example I don’t keep a folder of the sigils and demons or seals or anything like that that I’ve used.
If I can remember what the seal looks like, I don’t need to see it to summon an entity and if I can’t I’ll just google it quick and sometimes don’t even save them, I’m not as easily distracted by all the background images as I used to be.
Also there’s servitors on the forum that don’t take the normal spiritual form- like Luna looks like a my little pony sketch, because the overwhelming request I got was for spirits that would not scare people with their appearance.
So you might consider taking a look around, I know we have several free servitors on the forum that do good jobs with a variety of things that wouldn’t even look like anything to anyone but you.
Also to note, the average person may or may not feel weird if you summon around them. People with absolutely no knowledge or exposure can get real weirded out, or they may not notice at all.
If you do it while they sleep, often they have weird dreams and will mention dreaming about you and something off the wall the next day or a few days after.
So you can summon and have them not be aware but still have an awareness of it also, which may be more dangerous for you than for me.
I would recommend a petition style sigil opening for demons and the like rather than a full summoning. Basically just open the sigil, or gaze at it until you’re pretty sure they have to be listening or you experience some sign they might be, then tell them what you need.
Banish afterwards to remove the energy and it’s less likely to be noticeable as the spirit doesn’t come all the at into your space. Sensitives will notice all kinds of stuff though, so still depends on who you have to live with if you should try to only do this while your home alone for three minutes in the morning, or maybe in the bathroom with the shower running or some other slightly inconspicuous way.
Idk I can come up with ideas all day long, I just can’t verify if any of them might work for you lol
