Succubi and very connected with Lilith, I am not aware if she belongs to the Succubi but I guess she does. This hasn't hapenned to me but this may be Lilith, you could meditate on what that means. I've had many touches from spirits as well, on my legs, back, maybe arms, kisses on cheeks and about a couple of nights ago I felt a caress on my waist as well.
No summoning spells or Negative impacts. but i have been able to ask Lilith for power as well as others. i am only able to meditate through the nights and never am able to sleep. when i was i would always find myself surrounded by Succubi. that happened to me so much they would attempt to pretend they are human but i would always figure out in minutes that they were not.
You shouldn't feel cautious about the succubus. If you're building a good relationship with Lilith I wouldn't feel that way since Lilith I believe takes care of her own like any goddess would if devoted to them and strong bond.
The only feeling of the back of my neck when evoking or invoking an entity.
The only closet image of LilithI have is Lamashtu or Lilitu in the Babylonian mythology.
