I believe that life is cyclical in nature, and that when we die, we reincarnate, grow up, and die again and still return to this earth. Aside from the earth, I do not believe there is a place where the dead gather. We would always return here. This belief arose as a result of having the opportunity to see my previous lives.
I am not sure how it happened or what happened to me, but I was made to sleep, and while sleeping, my past lives were revealed to me as a film. Afterwards, I realized that this was not my first time on this planet, which led me to the conclusion that we would always reincarnate after death.
