the next step

I was watching some videos on dimensions. They're up to 12 now.  Using these 12 we can show where any physical object is in our universe.

What about thought?

I can think of something and it won't show up in a dimension.  Why is that?

I can think up a fork and them beat metal till it turns into a fork but the fork doesn't exist till I make it.  I think it exists the second I think it.

I think thought should be a dimension. Does that mean we have infinite dimensions?
