Whistling Room

I dont remember last nights dream except for something about someone whistling in a room, but the whistling came from two seperate locations, I was with a group of people, but I dont remember who they were and what we were doing, but I was following the whistling noise to see what was going on with it... I added two youtube videos to my favs that I think might have some sort of coincidence with the room whistle and the two persons who were whistling it, it was very similar to what I saw today when I went to see the final Harry Potter film, where two seperate girls start screaming for no reason, one after the other and then Voldemort starts mind talking to everyone there... the whistling came from two people in the dream, I also dont remember if the whistlers were male or female, its just a vague dream I didnt put much attention to what I was doing, I paid more atention to the discovery aspect of the dream... so maybe it was a kind of ghost hunting deal... I think I can safely say I have found something very close to what I remember from the dream, I was in a house in a room, and I heard whistling from two different origins, I dont remember the rest of the house, but being in a paranormal investigations would explain why I didnt think about the other people and did think almost exclusively about the discovery, I added a youtube video I found of a group called Chicopee Paranormal Investigators from Massachussets, so my guess is that I was there but the room looked lighter or whiter in the dream, it didnt seem old to me... I dont know if this dream has any coincidences with my previous dreams, the house is called Ventfort Hall Mansion, located in Lenox Massachussets...
