Yes, but I am just tired of seeing people simply ignore the fact that there are still possibilities that have not yet been explored. I have not experienced ghost first hand but I have been researching the subject as well as watching tv shows and documentaries on the matter .
Considering all the episodes of the Universe I've seen and the other specials about astronomy, it's not impossible to believe that these "ghosts" could be phantom glimpses into other dimensions. However, if that is the case (hypothetically,) there will likely never be a way to prove it. After all, we have no way of purposefully seeing or contacting other dimensions. Others who have studied the topic of the dimensions we can not experience or conceive of ourselves will know what I mean.
