Last Time I Saw Long Lasting Trails, (((( Smiles )))

They made a cross in the air right over where I live and it lingered in the air like lines.
But mostly the air has been clear and what I saw today was high in the air but close enough to see the plane and it was thin lines that didn't last long but...
are there different types of chemtrails can they do that???
And my mouth has been dry lately expecially at night as I drink lots of water in the day now. It can cause dry mouth?
Cotton mouth from whats in the air??
Dry out the air?
