A person who died, went to heaven, came back to life:

He said he met Jesus, & asked Him, where will I be living?

Jesus showed him a “landed estate” & said,“I know what each of my children like, & I custom build for each of them.”

Jesus said:
“In My Father’s house are many mansions (landed estates) ... I go to prepare a place for you.”
— John 14:2 NKJV

I’ve heard it said, that when a believer goes to heaven, they get a “glorified body” — which is you @ 20-something (w/o imperfections) for all eternity.

“the Lord Jesus Christ …
will transform our lowly bodies
so that they will be like
his glorious body.”
— Philippians 3:20-21 NIV
