I believe that I experienced through the whole process more than 15 years ago, you may still consider that I am speaking for myself, by my own experience though.
We (human) consist of a body a soul and a spirit. The spirit goes out at the moment of death, it marks the end of life and there's no return there till a resurrection occurs. That is, if you still want to go back after the spirit left you, you need God to resurrect you. This way the spirit is said to return to God at the point of death.
Then your soul and body start to separate. If you are deemed to be the wicked, you (i.e., your soul) will stay in Hades awaken. There's an additional process if you are protected by God. You (i.e., your soul) will be put to a sleep till the Judgement Day comes. In this sleeping state you won't feel time. So it's like this moment you die, the next moment you'll be resurrected for the Final Judgment. An exception is the chosen saints, just as indicated in the parable of Lazarus and the rich man, angels will carry the saints from Hades to the Third Heaven also known as Abraham's Bosom. Saints such as Moses will continue to work for God in Abraham's Bosom. They are not in a sleep. Samuel may be put to a sleep first, then he's awaken up (in the Saul/witch event) and possibly carried to Abraham's Bosom as well later on. Some saints such as Enoch and Elijah didn't experience death at all. They were carried to Abraham's Bosom directly.
Either you are sleeping in Hades, or awaken in Abraham's Bosom you are said to be with God in paradise as you are under God's protection. Unlike the wicked, they are awaken in Hades which is supposed to be tormenting.
