Haunted lodge at Mears State Park in Pentwater?????

I am interested in knowing if anyone else has experienced possible paranormal activity at the old ranger's residence in the park. My family and I stayed there recently and everything was fine except for strange happenings in the back west-facing bedroom with the sets of bunks. On the first night my wife slept on the bottom bunk by the window, our three children were in the others, and I slept out on the futon in the living-room. I slept fine, but my wife came to me in the morning while we were all eating breakfast and pulled me aside to tell me about her horrible night. She said that at about 3:30 she awoke to the  overwhelming sensation of tingles over her whole body, she remained still because she was scared, and then it felt as if someone was laying on her, at which point she began to pray. Eventually it went away, and she toughed out the rest of the night. Well, I decided that I would sleep in that bed that night. First of all, I couldn't get comfortable for the life of me, and something was bothering my 1-1/2 year old, who is a very good sleeper. I had to keep soothing him and laying him back down in his crib. Then I would return to the bed, only to lay there and wait for sleep to come. The whole time , it felt as if I were in the company of someone else, I was just very uneasy. I finally fell asleep, and then about 4:00 I awoke to the same sensation that my wife described. It was the most intense, goosebump type/ tingles/shivers I've ever felt. It started at the top of my head and went right down my body. It didn't go away for about 30 seconds. During this time, I was purposely looking around me searching for any visual evidence. As I sat up and started to say some prayers it all went away. Now, I was really up for the night, it was impossible to fall back asleep. I just watched the kids sleep, and couldn't wait for morning to come. I shared my experience with everyone, and it made for great conversation and pondering all day. I suggested that someone else stay in the bed that night for the sake of research, but there were no takers. I was there with my wife and three children, my sister and her daughter from overseas, and my mother and father. Anyway, I absolutely wanted to sleep there again the third night, and it started out better. I actually fell asleep with no problem. But at 4:30, I awoke very abruptly, opened my eyes to look around, and then the tingling began, it was so intense that it felt as if you were plugged in to some electrical device. Not painful, but strong, along with the sense of a presence nearby. I began talking out loud again, addressing whoever or whatever this was. As I continued talking and praying, it left slowly. I quickly went into the others rooms and told them it had just happened again. I decided that for the rest of the morning I would sleep in the other bottom bunk with my 5 year old. It was uneventful, and very comfortable. The experience was very powerful, and it has been all I can think about since. I have been trying to research the history of the building, and can find nothing. I wonder when it was built, who lived there, if anything bad or violent happened there. The address is 130 Cambridge, even though technically it's 400 Lowell, which is the address of the Charles Mears State Park, it's the lodge they rent out. Someone out there has to know something about that building. Or perhaps someone out there has experienced something similar...????  Anyone?
