Im not too big into dreams either, and servitor magic per say is rather basic and mostly chaos, they require upkeep
and i caught more than one story a servitor going rogue to straigth up evil, which is why i would not put my defense up to them.
I was guessing you knew your way around entities due to the sort of work you describe in your journals.
Golden Dawn, etc are all brimming with espirits one might subscribe for something like this
So if it were me being attacked i would
lock out all the real life possibilities like who or why would be trying something like that
Second, unless they were to use a servitor of their own to harass you there has to be some sort of contact, a way for you to strike back
i uploaded a booklet on combat magic maybe that would give you some ammo?
If i were in your shoes i would think that dream recall and control matter, so lucid dreaming, lately i noticed it's been dealt with on youtube
by experienced folk, however, in order to not be a sitting duck while working on that - as i said do prep work before going to sleep
Lesser banishing might do the trick no? Middle pillar? Before anything, confirm you are targeted, that fact must be true in order to make the right moves
