Strange House

I was walking to a destination in a neighboring city with my girlfriend, among others. I had walked in the wrong direction a few blocks which prompted us to use a map of a city that we all knew well. Suddenly, no one had direction. The map was covered with a kind of whipped cream substance that we kept on having to clear from the map in order to see it- much like rain on a windshield. Finally, we arrived near our destination- it was a house and we had a friend inside of it that we were to rendezvous with. I wasn't clear on the directions, so I called him. He told us of the cross streets. We wound up jogging the rest of the way because we came across a nice looking gravel trail. Once there, we went inside. It was a large house, apparently completely empty. My companions disappeared. I went up stairs to search for them but only found a endless maze of rooms that I feared to go into because each room contained 2-3 dogs that my presence raised curiosity in. Finally, back downstairs- still no friends found. Opened a door, a closet, and found the guy I was looking for but did not recognize him. Oh well. He spoke gibberish and pretended as though he didn't want to leave the closet and didn't want me around at all. I left and ran into my friends outside and tried to tell them of the strange experiences inside the house but they just didn't understand, or didn't care.
