I feel that I have lived in the past?

You did not exist before the moment of conception when the Lord created you.  And you will exist forever from now on. "Purgatory" doesn't exist.  Heaven and hell exist.  Here is the truth: The Lord Jesus Christ is God. Nobody can be good enough to avoid hell. The truth is that death leads to immediate heaven or hell, depending only on whether the person believed on the Lord Jesus Christ, or not. The truth is that the Lord Jesus Christ loves you and wants to bless your life freely :) Most of all, Jesus wants you with Him forever, and not in hell. It is too late to be saved, after death.

Believing on the Lord Jesus Christ means being forgiven all sins past and future and means going to heaven. The truth is that every belief except one will lead to eternal torment in the lake of fire for every person. Because nothing pays for our sins except the death and blood of Jesus, the sacrifice of Jesus that is already accomplished by Him . Jesus loves you! The truth is that the Lord Jesus Christ is God, and Jesus died on the cross to pay for all of our sins in full, and then Jesus was buried, and then Jesus resurrected from the dead. Nothing else pays for our sins, not works, not deeds, not religions. So the only way to heaven and to avoid hell, is by believing on Jesus for eternal life (John 6:47), without adding any of your own works (Romans 4:5). Believe in the Lord Jesus Christ to take you to heaven, and you will be in heaven, no matter what, guaranteed. That easy, thanks to Jesus! Tell Jesus that you thank Him that you will be with Him in heaven

We all have a past life but we forget it entirely as Gods mechanism erases those memories. If you do good deeds you can also be reborn by God.

If we want to believe something bad enough we can convince ourselves that it’s so.

SORRY NO INCARNATIONS U ARE BEING DUPED BY THE DEVIL.

It could be demonic influence - since by Christian faith demons can posses people, and possibly they did possess some other people in the past, then moved on to you.

Or they were simply showing false visions to you, to reject Christian faith, which does reject reincarnation.

I give up.  Do you?

No, many find familiarity in places and things in life. There is verified documentation of Past Life Memories and even the church once preached reincarnation.

It's just a feeling.  The facts cannot be demonstrated to be either true or false.

Your feelings are no different from those who feel they have a relationship with Jesus Christ.  Nothing can be confirmed.

It is an hallucination - like cult visions of jesus and mary and allah and brahma and.....  etc....

There is no such things as past lives.  Upon dying, a person goes to either heaven, hell or purgatory.
