Evil spirits taking over someone?

[Michel]

   Earlier a while ago, my ex girlfriend's friend calls me and brings up my ex(i don't know why she does) and says that a 'zombie has taken over her', well we were talking in creole so it might not sound right in english.  Anyway she says the 'evil spirit'  speaks for her(my ex) saying stuff and then when my ex starts talking she started crying saying she's in pain(she used to always complain about pain.) 

The girl told me she's getting skinnier because she doesn't eat because when she eats "it doesn't go in her stomach but the 'zombies' stomach."  I know this sounds weird but what is she actually talking about?  I'm thinking my ex must have some type of evil entity on her that needs to be cleared(by use of herbs, crystals and prayer?)  I didn't even care to speak but to keep the convo going I just put my 2 cents in.  Any1?

this may sound strange, but could the evil spirit simply be stress? stress can cause someone to lose their appetite and say things they normally wouldn't say.

for some reason, even with the mention of zombie possession, the thought of stress being the culprit came to mind.

hope she receives what she needs to regain control of herself...

I believe it can be stress, malnutrition(she barely eats), negative thought patterns, disrupted energy flow, and a helpless mind to name a few.  If i were to still be with her(I doubt it though lol), I would've been told her to start dealing with her emotions first with EFT or any other type of therapy, nutritional therapy and basically rewiring the mind to that of positivity.
