Chris – Well, you go to a new level of inner strength – bottom of the ocean without feeling as if you are drowning is a great feat.
The lobster is obviously already cooked, being red, so is a source of subsistence from your depths.
Breathing under water is another accomplishment, although you do not need air in the world dreams occur in. For sleep and dreams are a little experience of the world of the dead, with its experience of heaven or hell (nightmares).
You have an easy access to the world of waking life shown as the land – life out of the ocean/unconscious and waking type responses.
