In ways similar to when we are embodied, Paul seems to think we can experience things as a spirit apart from the body. He believes He could be out of the body and snatched, seized, possessed (Greek: harpazo-ed) by God to go into the third heaven or into Paradise.
2 Corinthians 121-5 (Concordant Literal)
1 If boasting must be, though it is not expedient, indeed, yet I shall also be coming to apparitions and revelations of the Lord.
2 I am acquainted with a man in Christ, fourteen years before this, (whether in a body I am not aware, or outside of the body, I am not aware -- God is aware) such a one was snatched away to the third heaven.
3 And I am acquainted with such a man (whether in a body or outside of the body I am not aware -- God is aware)
4 that he was snatched away into paradise and hears ineffable declarations, which it is not allowed a man to speak.
5 Over such a one I shall be boasting; yet over myself I shall not be boasting, except in my infirmities.

Peter also said Jesus, after he was put to death, went in the spirit and preached to the dead.
1 Peter 318-20 (Concordant Literal)
18 seeing that Christ also, for our sakes, once died concerning sins, the just for the sake of the unjust, that He may be leading us to God; being put to death, indeed, in flesh, yet vivified in spirit,
19 in which, being gone to the spirits in jail also,
20 He heralds to those once stubborn, when the patience of God awaited in the days of Noah while the ark was being constructed, in which a few, that is, eight souls, were brought safely through water...
Notice the KJV in the following says, "For this cause was the gospel preached also to them that are dead."
1 Peter 46 (Concordant Literal)
6 For for this an evangel is brought to the dead also, that they may be judged, indeed, according to men in flesh, yet should be living according to God, in spirit.
Distinguishing these idea and approving of one or the other should not determine our relationship with each other. God sees our hearts and whether we are humbly pursuing His Truth or not. I've changed in my understanding about many things. Through it all Jesus has never forsaken me.
