Apparently, Jesus did. They are called spirits. All are human. They are either spirits of those who have died or devil & those who were cast out with him.
After the resurrection, Jesus pointed this out to the surprised and frightened apostles...
Luke 24
36 And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace be unto you.
37 But they were terrified and frighted, and supposed that they had seen a spirit.
38 And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts?
39 Behold my hands and my feet that it is I myself handle me and see for a spirit hath not flesh and bones as ye see me have
Between Christ's death and resurrection he taught the spirits of the dead (he taught the Gospel of course)....
John 5
25 Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.
1 Peter 3
18 For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
19 By which also he went and preached unto the spirits in prison;
20 Which sometime were disobedient,..
(Note the Greek connotation of the word "prison" means like cage or confinement, not torture or hell and it is a place of learning if they are willing).
And why did he do this...
1 Peter 4:6
For for this cause was the gospel preached also to them that are dead, that they might be judged according to men in the flesh, but live according to God in the spirit.
He taught the same thing among the dead and organized his followers there, just as he did among the living, and the only difference is the dead cannot be baptized for themselves as they no longer have a physical body until the resurrection so it must be done before then and by a living person....
Paul, teaching on the reality of the resurrection mentions this almost in passing...
1 Corinthians 15:29
Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?
This idea of a vicarious substitution is very much in line with what Christ did for us in suffering for our sins or much of the Old Testament sacrifices.
There is also a spirit paradise, recall what Jesus told the man crucified next to him when the man asked Jesus to remember him... today, thou shalt be with me in paradise. That this paradise is not heaven and is a world of spirits is evident when Christ appeared to Mary on the morning of the resurrection when he came back for his body. He said he had not yet ascended to God (in Heaven).
John 20:17
Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
