I have thought about this too. Chuck Missler has taught about the "Physics of Immortality" and how we will be changed from what we are now to whatever we will become and he is very good at getting your thoughts going on this. He talks about dimensions and how we will see Jesus as He is, according to John and that means we will enjoy as many dimensions as He inhabits, whatever that might mean.
 
1 John 3:
 2.  Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
 
There is then also a great responsibility that goes with this privilege of having this station granted to us. Jesus said that if we are not faithful with that which is another man's, then who will give to us true riches?
 
Luke 16:
 10.  He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much.
 11.  If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches?
 12.  And if ye have not been faithful in that which is another man's, who shall give you that which is your own?
 
Whatever we will be when we are changed, I believe that we will have power to do what Jesus did in moving about through locked doors and traveling wherever we would like instantly. Such power could never be trusted in the hands of any who would use it for advantage to do wrong. That is why God must test us now to see what we will do with the props and temporary talents of this present world. If we are faithful with this world's jewels or talents, then He knows that He can trust us with true riches. That is why the very next verse in 1 John after describing the change that we will experience at Jesus' appearing, says this:
 
1 John 3:
 3.  And every man that hath this hope in him purifieth himself, even as he is pure.
 
If we have the hope of being like Jesus, then everything else must fall subject to that hope and be less important than that goal. It is a high calling. However even when we fail, He is still faithful and can restore us as we submit to Him and His will for us in everything. It is not a perfect performance that we seek to offer to God for that is impossible. Rather, it is a perfect heart of willingness to let Him be in control of us and our willingness to obey Him. This submissive heart and trusting Him is what He seeks in us and will reward as we prove it time and again through many tests and temptations. To him that overcometh...
 
I wrote a letter to my daughter where I used the movie "Willy Wonka and the Chocolate Factory" as an example of this. (The original with Gene Wilder, not that paltry remake with Johnny Dep.) I show how Willy Wonka was seeking a worthy heir when he invited children into his factory and put them through tests. Each child failed the tests and they were eliminated from consideration until only Charlie was left. Even though he too had failed when he drank the fizzy lifting drink, yet he was forgiven when he returned that all important piece of candy rather than take it to the enemy and seek his own exaltation or riches with it. By proving that he could be trusted with little, Wonka knew that Charlie could be trusted with the entire factory.
 
In a sort of similar way, this life is God's test with us to see if we will go our own way or give Him back our "piece of candy" or our own life and submit it to Him, or will we go our own way. If we pass the test with that which is not really our own (this life) then He will give us a life that is our own and power that He could never trust to one that is not worthy. God is replacing the one third of fallen angels with one third of worthy human beings. David Flynn is showing this very beautifully in his materials.
