The more you understand the more the dark forces will attack. The darker realm so close to us will use everything in their arsenal to change you back ignorance . It wouldn't come in the way of demons but they will attach a person through doubt. They will use our reasoning mind to create this doubt. To hold on fast to the light we need only remember they have no real power over us.

You were facing one of those attachs were the dark engery was manufested because you used artificial means to generate the experience. These type of trips are fine as long as the one going under is skilled in what to expect. The dark feeds on fear and what we fear the most is hidden inside us all and these engerys can tap into it. There isn't anything to be afraid of. The light will always over take the dark and we are made of light.
