Very interested in what you say! I've just finished a parasite cleanse (not Humaworm this time but similar ingredients). I always notice that my dreams are particularly vivid (in colour) during parasite cleansing and I remember the details. I have noticed this effect before. Also I sleep better.
I can't say I have noticed a change of role in my dreams but the clarity of the events is disturbing! Especially when you have forgotten what dreams are like!
