A whoopsie doodle of a dream,

I had a dream right before I woke up.  I have no idea what the heck I ate before bed that would create such a dream but dream I did. 
And now I'll share it with you.
I was at a library picnic (they only had one in the years I was there).  I was standing at the edge of the water when a guys in dress pants, white shirt and a tie comes floating past, face up and dead.  Right behind him floats a young kind and a woman, both on their backs, she in a dress.  I wade in, pull the kid out, carry him up the hill, lay him on his side and get the water out of him.
Once he was breathing I went for the woman but could pull her out of the water so I got her to the shore then ran up the hill to get the head of security (which the library didn't have unless you count me with a shag carpet rake but that's another story).  The head of security comes running down, he moved fast for a big guy who was on some tv show sometime, and picked up the woman to lay her next to the boy.
By this time the dead guy had an escort, a shark ??? and a crocodile (not alligator I could tell by the snout).  Security guy wades in nonetheless, kicks the shark, bops the crocodile on the nose and grabs the guy...uh ah... the part of the guy that's left and runs back up the hill past me holding the lower body of the guy by the guy's spinal cord.  No idea what happened to the other half.
But WAIT the dream isn't over.
The crocodile comes crocodiling out of the water heading for the woman and the boy but is momentarily side tracked by a side by side row of carved and painted wooden fish arranged on a blanket.  It nips one and decides it's not dinner and heads for the woman and boy so I grab a wooden fish and bop the crocodile on the head with it.  Croc turns and goes back into the water.
The boy lived, don't know about the woman and the man, well I doubt that half a man is better than none.
As I told the Old Pooh this dream this morning he asked why the security guy brought out the half of guy.  DNA I told him, instead of how the heck would I know why anyone in my dreams do what they do.
I think I need a nap.
