I have no more than a novice level of expertise in this subject but have found it interesting for some years. In the mid 1970’s I had an inspiration based on an assumption that to have mass a particle has to bend all dimensions that makeup spacetime; at the time I was convinced there were only four. The logic was simple as good insights tend to be, if you look at a particle and remove one or more dimensions it doesn’t exist from our four dimensional perspective. Leptons I assumed traveled at the speed of light and had no mass; they behave as if they have mass in photovoltaic applications but the Lorentz transformations indicate their mass would be infinite at their native speed. I proposed that leptons did not exist in the “Time” dimension rendering them weightless, fast, and stable to the point of immortality. I assumed that all particles could be built theoretically from their dimensional qualities if we understood the dimensions in a better way.

I know I can read auras

And Have seen ghosts...

But what's this?!?

Today I was talking with my cousin who lives states away and I havent seen her in years. I have never even seen her house or her room.

We were talking and out of the blue I smelled a musty, attic like homey smell that was like a house or room I have never been in, I felt compelled to ask her about the smell and she told me she had the attic room.

Can anybody tell me what that is?

It's happening more and more, either I see somthing and it happens or is true smell or hear, even feel somthing such as rain....
