The Ascension Vaccine, 3 days of darkness, Chemtrails & more

Is it true that Earth is being used to manufacture an 'ascension vaccine' for helping other beings in the universe to ascend?

Will the Sun really be blocked out for 3 days from 21/12/12? Would we need to stock up on food and water?

Are chemtrails a threat, is there anything we can do about them and is there anyway we can be helped.

if the body is so crucial for the ascension, then what happen to those human souls non in embodiment? (dead souls residing in astral realms waiting to reincarnate)
