I had a dream I was visiting a friend's house with the friend next to me, as we were walking up to the front door we noticed how pretty the garden was and how beautiful the architecture of the house and fountains were, it was like a mansion. and even though it was her house it was like she was seeing it for the first time. When I put the keys in the door the house started some crazy unfolding construction work and it was moving out towards us and I was terrified it would kill us, the sound was horrific like a wood saw really loud and we were trapped in a corner trying to get away, my friend was little and I was trying to protect her, it was completely overwhelming and it felt like we would die, I found a window of sorts and rushed to jump out onto the bushes to escape but then I woke up. It was really strange and scared me. What does it mean?
