The answer to your query is well substantiated by extraterrestrial evidence. You know that light you see near death? It is Scotty's beam. When you go toward it, you are transported into another dimension. The Fourth Dimension. There, you will be reunited with your dead horses and cats, along with your farty Grandpa, and together, you will roam the stratosphere of the planets in an alternate universe.
I hope this helps to quell your fears.
May the Force Be With You.
