Diver
A pushed-up mask is often a sign of a diver uncomfortable with their situation and their life-support equipment, beginning to lose control, and can most definitely be an early indicator of a panic spiral developing. It can often be be a reaction to some other precipitating problem that needs immediate correction or assistance.
Sometimes MOF is a sign of a fogged mask and the diver would like to see who they are talking to on the surface. Sometimes a train is just a train...sometimes a tunnel is just a tunnel...the light at the end of the tunnel is often a sign of a train.
