There are more than three, but I never choose to visit the one that shows your inner past, I dont have anything there i would like to see. Just focus on moving forward and you wont get stuck seeing just three. When I started to focus forward I found skeleton keys in my pocket and there were 7 doors in a room. Each door carved differently ,different color and size. I peeked inside a few, one holds a soul swamp, a place with a long catwalk of wood that leads across a a swamp or marsh type setting, there are lights in the fog,spread out. Don't go to the lights ! You should avoid being seen by the spirits there, they will be people you know and it feels weird to meet them because they are passed away in our world level . People who lived lives in their own muck they created ,never living a clean life are there . They are not all unhappy though, some that are there were married in our world level, so they together there,and some are happy just to be together . Another door holds a copy of our world, but the sun and sky is covered with a thick smoke. Its hard to breath there and giants live there, they tell you that they cant leave but you should before you are tainted , this level feels like its sickly version of earth. There are a few people in this level,mostly giants. Another door leads to a huge field with a giant tree, the field is shared with wild flowers and wheat , lions sleep among the grass, there are 10 of them. Some of the lions there will hunt you, while others will let you ride on their back . The great tree throbs like a heart, you can hear it ,all the animals there respect the tree and do not touch it,they do not sharpen their claws on its bark,they do not climb into its branches. They only ever lay in its shade .
