The weirdest thing just happened. I just exited Shadowgreen Cavern when suddenly a dragon comes out of nowhere. It flies several circles around me, runs into the steep mountain, flies up to the top of the mountain and then soars back down dropping dead right in front of me. Also as i mentioned in another thread there is a freshly slain dragon at the main gate of Solitude every time i fast travel there. These happenings didn't start until after i gained the ability to bend the will of dragons and i returned to Skyrim from Solstheim.

dragon suicide?

This is your Dragon. This is your Dragon on drugs. Don't let your Dragon do drugs.

Some powerful necromancer on skooma perhaps, creating weird spells.
