“Seth material” search engine (Jane Roberts)

Because you identify your experience with the regular line of consciousness with which you are familiar, you are rarely able to “bring in” any “other-self” material and hold it while retaining your own sense of identity. Such material may at times bleed or intrude into your own thought, where it blends and is not recognized. In such cases, it takes on the coloration of your own thought patterns. It adds to the overall atmosphere of your being. Without understanding or training, you would have to “lose” your own consciousness in order to perceive the “other-consciousness.”

Now: One experience was a dream of your own, in usual terms. The other “dream” experienced simultaneously was, instead, your muddled interpretation of vital experienced reality on the part of another portion of yourself, in another reality entirely; a dimensional bleed-through. Once you are aware of such experience, most likely you will also have others in “your” dream state.
