That is not Catholic doctrine. Are you sure you are one?
I'm very sure I'm Catholic. I used to have an incorrect concept
on death too.
There are couples of lines in the liturgy that support this and
from the bible aswell.
This is but one of them "Remember those who died with the hope
of being risen..."(The dead would not be able to remember God so
this words are spoken by the living instead)
Jesus descended into the kingdom of death(a place where the
faithful dead await for the Lord to rise them up) for three days
and this is said in the liturgy each week.
The bible says that Jesus promised us to rise us on the last
day( 3 times each in Matthew, mark, Luke and John). And it's not
the last day we see the world. Read what Martha said when Jesus
spoke that Lazarus was not dead.
Remember the apostles were all Jews and Jesus the Lord came not
to break the laws but to perfect it.
Read about Lazarus and Jairus' daughter who were being
resurrected by Jesus. Jesus said they were sleeping when the fact
was that they were dead. When His disciples didn't get it Jesus
used the plain word: Lazarus is dead.
This word describes it best: RIP
There are exemptions however but most people would descend to
the kingdom of death awaiting being risen on the last day. All the
dead would descend to this world that Jesus referred as the kingdom
of death.
However some of the apostles believe that when a man share the
spirit of Jesus he would be risen. Though there was no mention
when. But probably we can safely assume it is immediately just like
Jesus(3 days).
Most people however would descend to the kingdom of death until
the last day.
