Hello @littlescribe, I have quite a few experiences on both NDE or also called OBE's and talking to mediums. I do the OBE myself and I have many friends who can be called mediums but we don't call them that because they are actually real Shamans.
From where I'm from (Mongolia) there are many Shamans so we have easy access to them.
I will share more information about them in my own blog which I have recently started, you can read them here.
