What happens after death?

Are the possibilities that await us after death more numerous than we think?  Each person’s life experience is as individual as a fingerprint.  Could a person’s life experience determine what their after death experience is like?   Could some spirits reincarnate, while others exist in a spirit form that is able to pass between their nonphysical existence and ours through portals? Obviously, I don’t know the answer but I would like to hear the opinion of others on this topic. This is not a debate but an exchange of ideas so please feel free to express your opinion.
