You have some of it correct, however no one is in Heaven. "The dead sleep" until the resurrection(s). Jesus Himself is the "firstborn of the dead" via the resurrection. The dead are resurrected at "his coming in the clouds" and the living are translated.
Quoting: anonymous 77899003 Christians Do go to heaven:
Mr 16:19 ¶ So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
2Co 5:8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
(KJV)
Php 1:21 ¶ For to me to live is Christ, and to die is gain.
22 But if I live in the flesh, this is the fruit of my labour: yet what I shall choose I wot not.
23 For I am in a strait betwixt two, having a desire to depart, and to be with Christ; which is far better:
24 Nevertheless to abide in the flesh is more needful for you.
People in heaven:
Re 19:1 ¶ And after these things I heard a great voice of much people in heaven, saying, Alleluia; Salvation, and glory, and honour, and power, unto the Lord our God:
(KJV)
Jesus Christ is going to rule and reign on the earth. The believers will be with Him on the earth at that time. Right now believer's go to heaven to be with the Lord Jesus Christ because that is where He is.
