You can make up any crazy superpowers you want and say we might get them in the afterlife. That doesn't mean it is true. I am not saying what is a fact, I am saying what is likely. If there is an afterlife and it isn't logical or bound by physics or anything, then there is no point in even really thinking about it because it could be anything.

However, what ever is left of "you" is probably not going to be you anymore. If logic and physics no longer applies then all your human thought patterns and memories, created in your brain may not even exist. So even if some part of you went to this strange chaotic world when you die, it probably wouldn't be you.

It would be like if someone killed you then cut off your hand, then carried it around with them. Then they said that you are still with them. Yeah, technically your hand is a part of you and you are with them, but not in a meaningful sense since you would be totally incapable of thinking and are dead, and just a hand.
