I will spending quite a bit of time in the spirit world before I even contemplate coming back to Earth in human form. I feel there is so much to see in spirit world, I would be flying around space visiting different realms and planets. I will come to Earth in spirit form and do a "Nelson laugh" off the Simpsons at the people. I'll be saying you guys are stuck here on Earth while I'm flying around free from all the pain of living as humans.
If I was to come back in a next life, I would be choosing to be psychic, clairvoyant and medium. First things on the list of any return to human life on Earth.
