yes
Being that you are one of the few who actually has witnessed ball lightning, absolutely! I only wish you had videotaped the event.
Consider yourself extremely lucky to have witnessed that. which leaves me with some questions.
1. How can an electical orb, being not a solid object but pure energy, have the capability to "bounce"?
2. It "flared up" then dissipated with a puff of smoke. What would be "feeding it" to cause it to flare...and similiarly, what would have just as soon "popped" it?
I would like to state however that mammatus are not hail clouds, they are simply a sign of extreme instability in the anvil portion of a thunderstorm and not always indicitive of severe weather. As far as the wedge form, it would have been nice to have a photograph of that to verify if it was scud, inflow feature, etc...
