I highly recommend looking into Emanuel Swedenborg's writings. He was a Swedish scientist and mystic (and more) in the 1700s, who started to receive vision and became able to speak with angels and spirits. He wrote extensively about the afterlife, heaven and hell. Life on other planets etc. And it basically lines up with what most Near Death Experiencer's, astral travellers and mediums and similar describe nowadays.

At least some of his popular books like Heaven and Hell is available free online.
