Buried alive

Last night I had a dream I was in the middle of a desert. Yellow powdery sand stretched as far as the eye could see. Running straight through was a road made of clay. I was on a motorcycle racing across this barren landscape. A man clung behind me instructing me to speed up and slow down. I could see the end of the road ahead of me and I started downshifting. I wasn’t fast enough and before I knew it I was tumbling across the hot sand. The sand somehow collapsed on top of me, burying me. I tried to kick my legs and move my arms but it was useless, the sand just kept pouring over me.
