Roof falling in and more…

Something about my grandmas house and it was raining and the roof was gonna fall in. But it might have been a garage? And there was something weird about it? Like I couldn’t get out or something? Then a little before that there was something about this wild dog creature and somebody whistled (possibly me? or somebody I was watching) and it bowed and lay down.) then something about these two twin beds (possibly at my grandmas house?)
