A living human body is a soul trap. It's bound to suck something in.
If you insist. I hate this story, but here goes.
I died once. I was dead on the floor of a bathroom with no pulse for at least 5 minutes according to witnesses (felt like 5 seconds).
The other side was dark. All I remember was an ominous voice that told me that if I took one more hit of crack I could stay.
Then I woke up, feeling just fine, but it was 15 years ago, and I'll never forget it.
My interpretation of that experience was that once my body was incapable of functioning, my soul vacated it.
Then when the body began to function again my soul was "sucked" back into the soul trap. (1 single hit of crack, no matter how large, wears off very quickly).
The concept of the body being a soul trap is described well by Zecharia Stichin, even though there is much disinfo there as well.
