Unwelcome (revison # 1)

[LunaDeLore]

  Maybe there should be some reason given for why the person isn't welcome in the dream universe.

Some notes:

  You stepped into my mind
  last night as I dreamed wildflowers
  the lapwings swooped down
  and soon you were descending
  from a talon -- "stepped" doesn't seem to fit with "descending from a talon".
   
  I smiled as I watched
  you disintegrate into ash  -- ash is created when something burns, then ash disintegrates. So the line is a bit confusing.
  then disappear from my dream universe
   
  You’ve never been invited
  never welcomed there
  but I’m sure you’ll intrude again
  if for nothing else
  you’ll wannabe the overwhelming primrose -- "wannabe" is a noun, "wanna be" is the contraction you're looking for.
Why not just use "want to be" ? 
"overwhelming primrose" ?  -- This needs some explanation leading up to it, otherwise it doesn't seem to make much sense. 

  and it’ll be satisfying to see your exclusion -- This line tripped me up when I was reading it.
Maybe: "and I'll be satisfied"  -- and maybe a verb other than "see"
  once again
   
  Next time you could get buried
  under a mountain of gooseberries
  and shoveled into the back of a farm truck
  hauling prickly pears -- maybe use one of these fruits, not both
  then packaged and shipped
  to someplace like the Brazil -- typo, a "the" seeped in from somewhere and maybe just use "to Brazil" and leave out "someplace like"
  or even the Bermuda Triangle -- maybe leave out "even"
   
  Where you’d be swallowed whole -- this line is a continuation of the lines above it, it shouldn't at the start of a new stanza 

  as your existence gets digested -- "and" would be better than "as"
-- digestion happens in the stomach after being swallowed (even metaphors need a bit of logic)

  and the print on your birth certificate -- leaving a blank birth certificate? maybe the whole birth certificate should go, not just the printing?

  fades into the obscure -- "fades into obscurity" is probably what you mean.
I guess it's possible for something to fade into the obscure, but it reads a bit awkwardly. 
  
  Maybe then you’d never come back
  never step into my dreams
  uninvited. 

Next,

I think you made some good points and I will consider your feedback in revision.

Thanks so much for reading and commenting
