The only times I've asked for a specific symbol were just for fun, to see if I could manifest things, not to receive a sign. I manifested his name in a really funny (to me/us) way, and I also sorta kinda manifested a Snickers. I'll tell the Snickers story just bc it was so funny. It really reminded me that you have to be specific!!
A young couple at my aunt's church was getting married, and they couldn't afford a photographer. I'm not photographer, but I do own a decent digital camera, and my aunt asked me to just take some photos. No problem! I love helping people! My aunt was also the main person involved in decorating the church and pretty much running the show, so mom and I were there allllllllll day. I asked the universe (did not believe in God at the time, per se) for a Snickers. I specified that I did not want to purchase this Snickers. I would just find it or someone would offer it to me.
Well, as I started taking pictures of the decorations well before the wedding was to start, my camera battery was dying. You've got to be kidding me! So I drove all the way home not having any clue where the charger was because I had moved twice, hadn't even unpacked everything, etc. So I just start digging through every place I thought it might be. Then I remembered the last place I knew I had it was in the smaller pocket part of my backpack. I open that up, and boom. There's an empty Snickers wrapper.
I just sat there and laughed at how elaborate the story was to get me to find this stupid wrapper, and how the universe was like, "You said Snickers! You didn't specify you wanted the actual candy bar!" LOL
