I can recall several dreams I had of entering hell a while back and they were very real that I can still remember them so clearly until today so make it what you will. Here are some of the descriptions.
1) I was crossing a lake with all sort of corpses in them. I mean all sorts. e.g. bursting stomach with intestine all over, "inflatable" corpses, skin peeling off, semi-submerged corpses, hacked bodies, children, adult, olds, young, male and female all in the lake. I was crossing the lake to a nearby train station on the opposite side of the lake by the way. I think I also noticed several mountains surrounding the lake (big lake) but the mountains were fairly barren but yet I could see something sticking up like tiny trees. But there were not trees. The lake has light breeze and water was very clear.
2) Another dream was me wondering into another hell of some sort where I felt a bit like entering a cave that was damp, dark, slimy, stale air and with little sunlight. Then I saw a group of people, four I think, wearing white clothing with long messy hairs with a chain tight to their waist belts and the belts contain spikes that punctured their skins. I think they were "human mules" pulling in circle a giant granite milling stone. Their white clothing, around the waist, was completely soaked with blood. I saw that when they slowed down to take a break by removing their belts temporarily. I think I saw a girl. She looked sad, very sad but suffered in silent and yet did cry or complain. Just like someone has given up hope. She was taking off her belt.
3) Then to another hall where everyone was sitting reading books with the "master or teacher" in front of them. The room was a cave that was damp, dark, slimy, stale air and with candle light on the wall. They all looked at me when I accidentally walked into their room but continued reading. The room/cave looked a very long and never ending so I walked on.
4) Then to another room where every stood naked on a staircase like stand packed like sardines and someone walked in to give everyone a cup of water to drink ... then I woke up.
There you go. They were all very real for me and did not have the "abstract" feel to them and the only thing was I could not smelt the odour very well but I could feel the breeze all over so for me I think they were real hell.
How I got there I do not know but I also dreamed of visiting a place full of monks.
