New Testament demons are believed by some to be the disembodied spirits of the Nephilim, a half angel-human hybrid born of a sexual union between a
fallen angel and a human female.
Being half-angel/half human, upon their death they can neither ascend to heaven nor descend to hell but are trapped in a limbo region between.
These are the demons of the "dead relative coming back to let us know he/she is ok" genre.
Demons know everything about a dead person because they have been around since the time of Noah's flood and simply follow a person (or persons)
throughout their life.
Once the person has died, the demon is "homeless". It leaves; or it finds another human host (another family member perhaps). It can manifest its
presence physically using mediums, channelers, poltergeist or other "haunted" activity, etc.
It typically can manifest as the person it hosted in that person's life.
Fallen angels are part of Satan's ilk and their plan for humanity has never changed: kill, steal, destroy, deceive.
Part of that deception involves creating and exploiting the "ET" phenomenology. In that context, demons, who are still under their control in the
dark spiritual hierarchy of things, can be summoned to help "play out the game" so to speak.
