Thanks for sharing
Folks , mine story smiliar , sory my bad english, it is bla, bla , hope you get what i mean...
this summer in a place where i never been before....,
decide to swim and divedfor fun , dept was -7m, very clear water, deep was looking very alive
i find out a tunel by chance there., and decide to enter
at last point of the tunel there was a sun light hiting down , came back to surface to get a deep breath before dive ,
i relaxed and get deep breath and dive..the tunel was almost aprox 15m long ..
when i achive to last point my plan was to get breath the point sun hiting down .
but there was no exit and area was a long crack to push my head up was impossible ., a sun hiting from a thin large crack ...
at that time i said myself if you die here no one can find your dead-body ,
i was alone and no one can help me! , i stop and start thinking(1-2sec)
at that point there was a chance to ruturn back., but would be no chance to be alive..
i mean i would get BO at surface.,
at that point i said to myself (i know it is reeeeallllly crayz idea) you are a part of the sea(stupid idea but worked!)., you don't need breath and go back and come back here again
( when i think now.

... it is a very silly think and idea

)
i did very easily to come back to the enter of tunel and it is crayz thing , 1 sec i stoped at the tunel enter and than i looked into the tunel., the sun still shing ..and push my hand on the gate, no-fin ... i came up to surface.... don't know why i did it, i exactly remember all second and all minutes, it was really a good experiemnt for me.,
i sad myself never dive an a area not knowing very well .,
i wanted to share with you folks, being sedative gives a chance to return back
