God Squad: Yes! More signs from the other side

I feel like Michael Corleone. I am trying to get out of the signs-from-dead-people game, but then I get letters like this that pull me back in:

To quote you, "I am not sure" what to say. What I can say now, after hundreds of letters, is that signs from the other side fall into various types:

• Warm, invisible presence. No words, no special effects. Just a warm feeling of presence and love.
• Words plus the warm invisible presence. Usually, the words are a simple message, "I am OK." I like these messages the best because they are clear and comforting and not spooky (if you can ignore the fact that the message is coming from a dead guy).
• Words plus an appearance of a ghost. Dead people, according to my research, seem always to be translucent. Not completely clear but clear enough to recognize their features. I would like to simply discount the truth of ghosts because of all the possibilities of concocting such images to trick people or sell TV shows, but I cannot. The evidence of ghost sightings from non-drunk people convinces me that we are not alone and that our dearly departed occasionally find a way to remind us of that spooky fact … not just on Halloween.
• No words but special effects that do not violate the laws of nature. Butterflies that land on a coffin; cardinals that land close by; favorite songs that suddenly are being played on your favorite music station; someone wearing the same cologne; etc.
• No words but special effects that are just crazy. This is what you got in full measure, dear G and M, with your flying Yiddish book and your rocker-less rocking chair. Of course, these are the hardest to believe because they contradict the laws of nature (specifically gravity) and even Einstein could not find such a source of energy.

Keep your signs coming. They keep me up at night.
