Assalamu Alaikum Wa Rahmatullah
No one actually knows about this except Allah swt.
What matters is that you remember your deceased ones by reciting Quran for them and praying for their souls and to give charity and gift the reward to them because now they have no access to good deeds except someone does for them.
It actually does remind us how empty handed we ourselves will be in the next abode and motivates us to gain more for our next life.
