I've had this feeling in the past, sometimes I'll shift into this altered state of consciousness where I'll feel like I am a vessel that something else is using to speak through me to the person. Sometimes I won't even be able to remember what I just said, other times It'll be less intense and I'll get nudges to say things and then have to use my own intellect and creativity in how to convey that information (or if I even want to convey that information at that juncture to them)

So yeah, I like the idea that we're all part of a larger being and sometimes we are used (if willing) to be a channel for higher level entities.

Have you looked into mediumship at all?
