[Science fiction] If hyperspace exists, does hypospace exist?

Does there exist a dimension where you could travel for days at high speed, only to jump back into normal space and find yourself five metres away from where you started?

Would there be any practical application for such technology?

Great way of preserving things:

You could broadcast with EM in such a hypospace and treat it as mass storage, as days later your broadcast could be received but an antenna meters from the start.

If relativistic speeds still dilate time you can use it like a lifeboat - go as close to the speed of light as you can in hypospace and millenia later you could be recovered from the same spot frozen in time - zero chance of the life sustaining machinery breaking down as the machinery was the universe. Only have to hope someone knows where to look for your hypospace egress point (but then again they have all the time in the world to look for you!)
