Can a phenomena exist both in a space & time continuum & "outside" the space & time continuum?

It is possible that there are multiple space/time continuums (alternate universes).

In this respect there would necessarily be a phenomenon outside a space/time continuum - another.

There would also be at least one phenomenon that was common to all space/time continuums.

I've been thinking about something similar the past few days after hearing the term, "non-spatial consciousness", by a proponent of duality.

At first thought I considered this description as very relevant. But as I was looking out the window, thinking of how non-local consciousness is (and which is why I believe in duality), I realized that with no space, or no anything, consciousness couldn't be NON-SPATIAL.

Thinking further....consciousness still would consist of possible intelligent qualities, right? Hmmm...,,lets see...how can that even be true, when there's no forms of anything in existence (such as a brain) in order for it arrange it's intelligence and deliver the thoughts. Emotions.....pure consciousness would be without feeling or emotion. Sensory tools would be needed in order to produce emotion, it would seem. How can such an autogenous consciousness have ANY power or "abilities" if there were no space, no forms, no dimension, no vehicles, no stress to produce resistance or contrasts. Pure consciousness would just "be". What good is energy without a product to fuel?

I know your question is asking something different, but my above thoughts lead me to my answer...a phenomena requires some tangible dimension in order to produce any phenomena. There's possibly a dimension of thought that has different qualities then that of the earthly realm but the possible phenomena that could exist there would not be of the same consistencies that would be produced in this dimension.

Possibly. Some sub-atomic particles can exist in two places at the same time. One spot traveling forward in time, while the other is going back in time. "In a universe that has no beginning and no end,anything that can happen, wil happen".

Yes, Its your "subconscious".
