I had a couple friends over weekend before last, and after some chatting and a couple drinks, I casually suggested one of them send me an object mentally. She had never done this with me before and she sent me four different objects total.
With the first one, I saw straw, like maybe a scarecrow, but my instinct told me to go with the properties. (Sometimes I can tell if I'm just getting the properties or the exact item.) So I said, "I'm getting straw." She said, "I sent you a red basket." She sent me a second object and I got simply a big orange ball. It was just too simple so I figured I had missed it, but I said, "OK, I just got a big, orange ball." She looked astonished, almost uncomfortable, and said, "I sent you the sun." The third thing I saw was definitely black and had a large, solid shape to it -- long. I wondered if it was a whale. Finally I said, "It's black; it's long, maybe cylindrical." She said, "I sent you a top hat."
We took a short break and a few minutes later, I asked her to send me another. This time I got a blanket, very clearly. Again, I felt it was too simple, but I said, "OK, I got a blanket or quilt." She said, "I sent you a green blanket." She was a bit freaked out over it, and she wanted to stop because it makes her head hurt. My other friend there, with whom I've always played the game with incredible success, said that it makes her head hurt as well. They both agreed the pain comes in the center of the forehead. So while I was disappointed, I didn't request any more objects. I am going to find out if it makes any of my other friends' heads hurt.
So far, the exercise has worked consistently with whomever is willing to do it with me -- except my husband, my cousin, and my brother. I was starting to conclude that it only works with females, but recently it worked with a male friend and in the past there was another male friend it worked with. So I don't know exactly what the criteria are at this point, or if there is a certain type with whom it works best.
