Esslesiastes  12:7

Then shall the dust return to the earth as it
                  was and the spirit will return to God who gave it

Our spirit does not stay here for any reason. The ghosts you are seeing are not human, they are demons.

2 Corinthians 11:14

                                            And no marvel! For Satan (and his demons)
                                            himself is transformed into an angel of light.

Demons are able to appear as they like to get your attention or use you to become famous and deceive.

Demons can appear as shadows,relatives,objects,or any person that has died.
Sometimes they don't appear in the house and will use ways to disrupt your family.
They will open doors,move things, cause things to disappear, attack you or your family with mental illness,schizophrenia,depression,cancer,bad dreams, visions,  hear footsteps, flies on the window especially in the winter when they are not supposed to be there,write messages on the walls,voices, light flicker, medical problems that the doctor can't detect,
                      Deuteronomy 18: 9 - 12
9 When thou art come into the land which the Lord they God giveth thee,thou shalt not learn to do after the abominations of those nations.

10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire,or that useth divination, or an observer of times, or an enchanter, or a witch.

11. Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.(psychic)
When you look for help, do not contact a psychic, a paranormal investigator who uses psychics nor use anything that communicates or detects spirits.
No need to use these people as you already know the spirits are demons and the Bible says not to use these people for any reason. These people do not know they are in contact with demons and believe they are contacting the dead. They don't study the Bible!

Demons have a biblical legal ground to haunt your place because someone committed a sin in the house.

Some legal grounds could be murder, suicide, abuse , evil practice like witchcraft or voodoo , use of a ouija board and much more.

Deuteronomy 7:26
Neither shall you bring an abomination into your house, lest you be doomed to destruction like it. You shall utterly detest it and utterly abhor it, for it is an accursed thing.

                                           Jermeiah 10:2

Thus saith the Lord, Learn not the way of the heathen and be not dismayed at the signs of heaven; for the heathen are dismayed at them.

3 For the customs of the people are vain: for one cutteth
a tree out of a forest, the work of the hands of the workman, with the axe.

They deck it with silver and with gold; they fasten it with nails and with hammers, that it move not. (christmas tree)

5 They
are upright as the palm tree

Bringing a Christmas Tree into your home will give demons a legal ground to haunt you and your house.

Not only will your house need Deliverance from demons, you will also.

How to end a haunting

Become a Christian
Study the King James Bible
Confess your sins to God
Remove all cursed objects (read the Cursed Objects article on my website
Forgive everyone who has ever lived in your house.
Say I cover myself and family members with the Blood of Jesus Christ.
I bind you in the name of Jesus Christ.
I bind you and put all the demons in this house in a box filled with the Blood of Jesus, shut the box and seal with the Blood of Jesus Christ.
Father I request Giant Warrior Angels to help me fight.
I attack you from the Third Heaven.

Mark 16:17

Jesus gives all Christians authority to cast out demons in His name.

I command you to leave in the Name of Jesus Christ.
I cast you out in the Name of Jesus Christ.

Repeat this for an hour a day . They will fight back , but  will eventually leave.  Don't let them stop you.
Record it and play it as often as you like

Do daily Deliverance, the cast out of demons from yourself because demons transfer.

It is a requirement to do daily self-deliverance because we all have demons inside of us, including Christians.
