There are no inter-dimensions.
It won’t make sense if I try to explain it, but there are reasons there are only three spatial and one temporal dimension. Nothing else is possible or ever will be.
As for the word itself.
A dimension means a measurement.
It requires three measurements to describe space.
It requires a fourth to describe change (time)
When nitwits talk about 11 dimensions that does not mean 11 spatial dimensions exist. It means it takes eleven measurements of causality to describe a behavior.
Most of these people are telling pseudoscience fiction for entertainment purposes the same way women go to fortue tellers and card readers. That’s all. It’s fun. But like horoscopes it’s just entertainment.
