Tony Communicates with me at his Wake

Last night, Tom and I attended a wake for one of his former high school teachers. I haven't been to a funeral home since my dad passed in August, 2008. As soon as we walked in the door, I got my tell-tale headache that there was a ghost or spirit present. In fact, I know there were at least two there (there were two wakes going on). One wake was for an older woman and the other was for Tony, Tom's former teacher. Tony passed from a brain tumor and had 5 sons.
We were standing in line to sign the guest book and I kept hearing "Maura, or Mara, or a female "M" name. I don't know who that is, and checked that Tony's widow's name is Pam and his sisters' names don't begin with "M." I got the sense that the name belonged to an older woman that was being waked down the hall in another room.
Once we entered the crowded and noisy room full of people talking, laughing and carrying on, I stood in the back. I didn't know anyone and Tom knew many people (former classmates, teachers, and people that belonged to that church school). I was standing with my back to the wall talking with my father-in-law and I felt a finger poke me in the back so I turned around. No one was there. It poked me again, I knew that it was "Tony" playing around to let me know he was there. My father-in-law noticed someone else he knew came in, so he walked over to talk with the man.
I wound up standing alone at the back of the room and sensed that Tony's spirit was poking his head into small groups of people talking, and turning his head as if he were trying to hear what they were saying about him. It was pretty amusing to watch. He really seemed to be enjoying the crowd of people there to honor him. When I later told Tom about this behavior, he said "That's exactly the kind of thing that Tony would do! He was a prankster in life. He loved to joke around."
The other thing was that whenever various younger men walked by me (there were a lot of younger men from 20 up there), Tony "told" me which of them were his sons. I knew that there four sons, but Tony pointed out three. One was a taller man wearing tan slacks and a checkered button down shirt. He then showed me another of his sons that was wearing a dark suit that walked by me. The third son was standing in the hallway wearing a black shirt, tie and pants.
Tony kept nudging me to tell that son dressed all in black that he was still here and actually enjoying seeing who came to honor him. I was reluctant to do that, however, because of the religious beliefs of the family (which is very sad). The family's religion thinks that mediums "talk to the devil." It's really frustrating to me, because I could've provided some comfort to the family. I heard and "saw" Tony, and know that he was grateful for the show of love and support during his wake.
