How is the last option of the poll even relevant to the topic itself?
Even then the poll doesn't make sense anyway. How could you even know that you dog/cat (no other animals?) is able to sense the presence of a ghost? Does he/she tell you so? I don't think so. Well.. Ghosts? I wouldnt be surprised if your cat was talking also.
In a discussion, it would be nice if we had nog misunderstandings, right? So wouldn't it be a good idea to get to be sure that we're talking aobut the same. Therefor I wan't you to first answer a few questions. What are ghosts? What are they made of and how do they live? How do you know you see a ghost? And last but not least, can you prove us ghosts do exist? And the latter being the most important. Until we have proved their existence, isn't it better to take the default position and conclude they're nothing more than a myth, a possible illusion created by yourself?
But hey, don't put all that effort in an attempt to answer the questions, you won't succeed, because it is impossible. There has never been good and accurate evidence of ghosts. You're only 12 years old, are you willing to say that you, a child without a full comprehension of the world, knows better than hundreds of years of science? Knows better than all those scientists who have studied this or disproved the existence of ghosts in multiple ways through different branches of science?
I know some people expect an essay of some sort in which I disprove ghosts, but guess what, that is impossible. Not because they do exist, but because of the mere fact that disproving something is impossible. If I want to accurately disprove the existence of ghosts I would have to prove two things. First of all I would have to prove the existence of everything that does exist, litterally everything. And after that I would have to prove that, next to all that I have just proven to exist, there is no space left for anything else to exist. And this is impossible.
So again, to get this thread a little bit more accurate, you'll first have to put up some evidence before continueing.
And no, this is not to put you down, this is just to get some reasonable thinking in you. You won't mind some brain food, will you?
