Would like some help understanding a bizarre dream?

A few nights ago I had a fairly realistic dream where I was in a house I didn't recognize in a bedroom talking to my mother (I don't remember what the conversation was about sadly) when there was an earthquake and the floor beneath us began to crack and crumble away into large lava pits with a creepy orange glow, in some places it was so unstable it seemed almost like quicksand. My mother disappears as though she was never there to begin with and I somehow make it outside, strangely I seem to easily avoid the unstable ground or falling into the pits and cracks. I end up outside in the driveway of my old house from childhood where the ground is in similar condition and there are several large trucks driving up the road and into the cracked driveway and people I don't know start coming out saying "Its time to go" in a frantic sense so I start to walk towards them and unfortunately I wake about that time before I could see what happens after. Any thoughts?
