I have a question on c4's, particularly my succubus. Do C4 binding's talk to you and /or come into your dreams? or is this c4 more of touching rather than communicating etc? Or do they talk to you later on or idk *shrugs.

if ur abilities r developed, class doesnt matter. if not developed then also class doesnt matter, because u may not be able to interact with them.
class plays big role in getting results, for ex. c5t3 protection is better than c4.
also interaction depends more on individual spirit\entity.
i have only felt djinns entity most strongly. but i think they have ego. they may become dormant if not properly cared and given time.
i have succubus, i makes me wet while asleep, she arouse me too much that i wet, i dont like it. i told her to stop. she has reduced the frequency i think.
i think she wants her sexual energy no matter what.
i have c4 and c5t2. i felt both similar.

Yeah, my ubi has been pretty warm lately and touchy feely lately. I think I heard her one night, she might've hummed to me one night but it was pretty freaky to me at first. Felt her a lot last night, nothing sexual yet, bonding process still.
