I recently stumbled onto a very powerful and reproducible technique. The best finds are always tripped over.
Many of us have had the experience of creating a "portal" and walking through. There are various ways to do this. For example, kneeling in front of a wall, placing your hands on it and de-materializing the substance of the wall and walking through. More often than not, people tend to report one of two things:
1) getting caught in a nebulous, unformed sort of void
2) Moving into a new scene which is quite random in nature.
The result in (1) is quite interesting. In a certain sense you have lost your dream visuals which is one major simulated sense in the dreamspace. So if one sense has been lost, why not leverage some of your others?
I have found that a combination of the following tools can help me manifest a desired target location:
a) Feel for some object consistent with the target.
b) Listen for some sound consistent with the target.
c) As always, intention and confidence will be part of your success.
I will provide an example. I walk up to a wall, and decompose it. I find myself in a void. I rip open a hole in the nebulous fabric. I feel for the banister of the basement stairs of my old house. As I begin to walk, I listen for the sound characteristic of walking up a wooden stairway - and of course I hear just that.
What I have found, is the more dream senses that are exercised, the more clear and well formed the new dream scene becomes. Voila ... instant dreamspace teleportation to a specific target location.
This observation and method should be generally broad enough for anyone to apply. Just choose your target and anticipated sensory input wisely.
Good luck!
