Can you see ghosts if they're your siblings?

Many people have different conceptions and beliefs about ghosts, as the evidence for them is frequently disputed and not believed (or only believed to a certain extent), and therefore it is impossible to provide a valid answer for this question.

Nevertheless, if one does believe in the supernatural presence of ghosts, then it is presumable that they may be siblings of the observer as well, although it must be stressed that there is no solid evidence to prove for or against this.

The loss of a sibling can also deeply affect a human, hence one who has suffered the loss of a brother or sister may, in their grief, hallucinate and be deceived by their minds in belief that they have seen them alive after death.
