Is it the opposite if you go to hell?
I would suggest that religious doctrine will not provide real answers, but the ancient philosophy may be your best bet for perspectives on these issues. I would suggest that reading the Upanishads ("A step down from the absolute") would provide some good clues, and some of them relate to this question. In philosophy, an acceptable answer to such questions traditionally can only come from within.
I've been studying The Mentor paperback edition (New American Library) which I purchased nearly 40 years ago; this interpretation is by Swami Prabhavananda with Frederick Manchester, and is a somewhat easier read, but lacks explanatory footnotes; this is a slight disadvantage, as the originals were oral compositions, and it appears that there was once an oral tradition (the originals were part of the oral tradition, and were not written down until much later) that included additional explanatory material.
One of these asks the interesting question "Have you asked for that knowledge, by which we may know the unknowable?"
There is available online, Muller's 1879 translation, which is an excellent one, though a very challenging read, however his translation includes excellent footnotes, and a good preface as well, plus commentaries and transliteration tables. It can be found here:

My impression from what these ancient "saints and seers" (philosophers) have said is that we carry memory with us when we leave the body.
"Many lives we have lived together, Arjuna; I remember them all, but you do not." -- Prince Krishna, in the Bhagavad Gita.
"Memory is the Glory of Mind"
"When a man dies, he becomes one with the existence, but without losing an individual point of view" -- the late yogi Chiranjiva Roy, former atheist-communist businessman.
