First of all when i get killed How do i get revived and cannot move?(in the next round i act as ghost but can do alive things but if ejected i end up as normal ghost)

Second of all how does all of these this only happen to me?

Third of all how can i see pass walls and why are those black things glitched?

Fourth of all when i Kill as impostor why do i glitch and cant move?(same as the first one in the next round i become normal again)
