Have you had any interesting experiences with tunnels in your Lucid dreams?

Please post here if so.

For myself,I have been Lucid a couple of times while my dreambody was being hurtled at high speed through dark tunnels just before waking up.

Other times,I may be riding in the back of a car with DCs or in a train going through a tunnel while I become Lucid. The other night I became Lucid in a train tunnel and stood up to fly away.A DC next to me grabbed my hand and said "don't do that here" These tunnels are very interesting to me.


BTW,I don't ride in cars too much and there are no passenger trains where I live.
