Here is a simple, reliable method, I have developed, to create your own personal realm: Get a poster of a pleasant scene, something bright and sunny. The bigger the better, but standard poster size will do. Hang it on the wall of the room you are going to project in, or another room close by. Get a small spotlight and set it so the poster is highlighted when the main light is turned off, a normal directional bedside lamp will do. Place the light under, or above, so the light spreads out over it giving a diffused effect illuminating it, a bit like a movie screen.
Entering your custom realm: When you project, go towards the poster, keeping your mind blank. Don't think about what you are doing, just gaze at it and move towards it. As you approach it in this way, your subconscious mind will be tricked into creating an astral realm exactly like the poster. Just move up to and into the poster. It is like stepping into another world. Everything in this world will be exactly like in the poster. It will appear to be a normal three dimensional world, an exact copy, indistinguishable from reality.
To customise this world: Cut and paste small pictures of things, or people, you want to find in this world with you when you enter it. Don't just stick a whole picture on the poster. Get scissors and cut around the object, or person. Try and find pictures that are approximately the same scale as the poster. If you cut out a small picture of someone, living or dead, your subconscious will create a thought form shell of them and they will be there waiting for you. This may be an excellent way of communicating with those that have died.
Spirit Communication: (I have a theory) The subconscious creates this thought form shell of a person. This shell can be animated by the perfect, detailed memory of your subconscious. But, if there is love there, between the projector and this created person, the spirit of this, diseased person, will be drawn to this scenario and will use this opportunity to communicate with the projector, by animating the created image of their body.
