Funny, that.
I usually get strange dreams about aircraft crashing when I'm stressed and need to reset my grounding.
I think the worst dream in that respect was recently, where I dreamed that I was at the airport, and one of the landing planes - an Airbus 380 - crashed big-time.
When I think back on it, it's just like I can still feel the heat from the fire and smell the stench of burning plastic, fabric, fuel and meat.
