Well, one thing I do before EVERY 'Session' is Pray and Give Thanks for the Sacrament for just that reason! I don't want any unwanted 'Entities' messing with Me.
I've had plenty [[ Almost TOO many for one lifetime but given that I'm a 'Pisces/Aries' cusp, which is pretty rare I've been told, it's MY 'Normal' to have Paranormal happenings ]] of crazy things happen WITHOUT using anything at all, especially being attacked in my sleep which the 'establishment' calls 'Sleep Paralysis' [[ I disagree with it just being 'A Nightmare' ]] and of waking to have some 'Thing' in the room. Others has witnessed this as well so I know it wasn't just me.
But anyways, I've been taken places a couple times while on DMT but I cannot say that I have been PHYSICALLY 'Abducted', no.
I think it is entirely plausible that the 'Astral Body' can been snatched away involuntarily, thats why I Pray and Give Homage before partaking, for My Protection and, it works, at least for Me it does.
Everything I say here happened in My own Imagination. The more fantastic it sounds, the more you can count on it being in the realm of Dreams,
