I sure have when I was younger and took lots of drugs. I know most of you don't believe in God or anything and that's OK but here's what happened to me.
I was younger like I said and not the best choice maker. I took a giant line of ketamine that should have killed me. I passed out and everyone around that I was in a normal K hole, which happens, aside from the fact I was foaming at the mouth and convulsing. This was an OD I got lucky to get out of.
Once I went down time and space slipped away from me. When time flashes before your eyes it isn't so much a flash. It was more like youtube video bar I could move back and forth of my entire life however and wherever I wanted but I could go inside the frame and visit my lifes moments to watch from a second perspective. I was the one in control and it was surreal.
This lasted a while, to me at least, I don't have a real idea of how long I was out. It went on until I used actual thought instead of just kind of floating and going with it.
At the point I realized this was my life flashing before my eyes i felt pulled hard and smashed into a tunnel with white at the end. The tunnel itself seemed like the only thing keeping me from being lost in the blackness all around. When I got to the white at the end you can debate whether it was God or not.
All I know for 100% is that this omnipotent white light was concious and as I talked it communicated without talking by sending like, energy that changed my feelings and senses. I lost it being 19 and said vividly please don't let this happen, I'm too young. And with that I felt a calming peace wash over me and I hope up with foam on my face and threw up hard.
Truth be told it wasn't scary or anything and that experience is what calms me knowing death is going to be OK when it happens no matter which way it comes.
