Dread feeling

Had a dreadful feeling two morning's ago.  It was intense.  The only thing I can compare it to is climbing when slowly you realize that you are overextended, and the possibility of a fall grows, but that the consequences are catastrophic.  It is a terrible feeling and luckily rare.

I don't know why I had such terrible foreboding.  I kept a keen eye all day long.  Nothing.  The weather was rather bad, but we worked all day and I could see my boat all the time.

 

It improved rapidly.  After lunch I felt fine and normal, a bit suspicious, but back to normal.

 

If anyone has any explanation I'd appreciate it.  I haven't heard of anything yet.
