First nightmare. Pretty traumatic..

[xhayatox]

I have never in my life experienced any nightmares. I've always been able to go to bed successfully, and sleep peacefully. Now, last night.. I went to bed as normal, and fell asleep. I started dreaming and I remember being in a church or something, and a priest gave me a cup that contained some kind of green-tea. I drank it, and the next thing you know, I feel my soul being purged out of my body. As it was getting purged, a green spirit/devil appeared out of me, as I was purged. It started screaming, and the dream shifted, and then I finally woke up in a panic. What exactly.. Did I experience last night? Like I said, in my dream I felt my soul being purged out of my body. It felt as if the sensation was actually happening. How is that even.. possible? How can a dream induce a sensation and make it feel like it actually happened to you in real-life? What's going on? Before I went to bed, I had a lot of soda to drink. I don't know if that contributed to me having this freaky dream, but yeah. So, overall. How would you guy's explain what happened to me? Did I experience a nightmare? What in the world happened?
