I feel there is another danger. When your spirit leaves your body as an empty vessel on the bed, its lying there with all doors and windows wide open. Other spirits can enter your body while you are out exploring. This should be practiced with caution.
But still a very good and informative read.
Thanks
Indeed, there is a bad part of it. It depends on the level of connection between your soul and spiritual dimensions.
If you create that bad environment around you it would literally affect to your experience directly.
So it's totally about the figment of your imagination and the meaning that you are constantly putting in.
Explore and research it more :)
