Lately I've discovered a type of mediumship used in 19th century seances that is rarely encountered these days: Spirit Trumpets. It is best to do this with another person because it's not likely that you will be asking the questions since you're in a deep trance(although you could try it on yourself but it sounds hard).
These spirit trumpets are for the phenomenons of 'direct voice' communication and sometimes materialization(the spirit can materialize objects to appear from the trumpet like roses, jewerly ect.).
How this works is that the medium have to be in a hypnotic trance state. You have to be in a really dark room with little little sources of light or even pitch dark(you will be able to see the trumpet). When the medium makes communication he/she will have an ectoplasm coming from one of their physical sources(mouth, ears, nose) and that ectoplasm will go to the trumpet. Note that ectoplasms are not always visible to our naked eyes but cameras well.
It is noted that when the communication starts and everything is set, the trumpet will start to levitate in the room. While asking the questions, you may get a respond or it may even materialize objects as a form of gift to you.
I made a paper trumpet since I heard you can make them out of almost anything you want but I don't know if it will work as good as an aluminium one. Worth giving it a try!
