Stearn Robinson - Tom Corbett Interpretation: Another form of obstacle dream.
If you observed the cavern entrance from outside, you can expect that your circumstances will gradually improve; however, if you were in it (or fell into it) and couldn’t get out, you may be up against some hostile influences which could frustrate your ambitions.
The seriousness of your opposition would be indicated by the depth of the cave*L If it seemed very deep, you should reconsider your goal.
