So, the technique is pretty easy. Take an individual you would like to have a dream with. Get to know them personaly if possible. And spend time being interested in him or her and give them your undivided attention. So, through attention and interest in the other will bring you and the other into the same dream. The person, in my opinion, must, and I mean must feel a sense of trust with you. The evidence that I experienced personally was the solidity of the dream and the creative art she drew me that resembled the color and imagery of the dream we shared. It is kind of a touchy issue so we didn't talk much about actually experiencing each other in the same dream but in her own way she was telling me that we connected on the same wavelength.
