Psionics/Absolute

I am trying to create a original character and I was wondering if someone with psionics like Omni or Absolute Psionics could manipulate dreams put more accurately Oneiric Energy

Which brings to my next question what is the difference between to and can someone with either power set manipulate use the others ability

Why does Absolute Psionics have Omni-Manipulation, @AzQth ?

Is Dream Manipulation a power that is apart of Psionic’s

If you are the Source of Psionics and has Boundless Psychic Energy, Inherent Omniscience, Meta Teleportation, Omnikinesis, and Omni-Telepathy, wouldn't you have Omnipotent Psionics? If not, why?
