On a daily basis I see and communicate with God, my guardian angel and other angels, and souls and spirits. That includes demons. As others have commented, we are taught at an early age not to discuss it because it makes us and our families look bad. Is it all about public perception or reality? If you want to see and communicate with God, do it. If you aren't sure how, contact me and I will work with you for you to get yourself there.
As for atheists and others who are afraid--dear heaven I love them. Their fears and doubts make real the strengths my physically weak body has been given.
