Not sure if this fits here but a friend turned me on to this. Nicolai Kozyrev was a Russian astrophysicist/astronomer who found that working with a concave mirror produced telepathic and other experiences in addition to predicting the future and remote viewing. There's a lot on youtube about it. It could be used for communication with the other side. I just ordered a few concave mirrors and hope to work with them with my friend in January.
