Info on Lucifuge?

I’ve had a few things happen recently that have made me consider invoking Lucifuge.

  • Dream of man with weird horns and fawn legs, accompanied by 2 stags
  • 2 deer near me at 9:45 pm
  • Deity energy reading:
    -A bed of moss and vines, upon a large rock, an offering of milk and honey, to a large stag, with uncountable number of antlers

Is there anything I should before doing it? Thank you.
