Random Animosity?

Is it just me? These 2 weeks I have felt some form of silent dissatisfaction from 2 people in the house. You know what I mean...they don't say mean things to you, but there's something odd about their body language towards you that make you feel uncomfortable around them...? The 2 people are:

Cynthia - oddly enough, Cynthia and I got along really really well at the beginning. Technically, I still have nothing against her despite certain qualities in her personality (will be discussed in the future) but for some strange reasons, she seems to be verbally attacking me these days. And the way she does it is very casual and off-handed, so no one seems to notice it but me (or they do but they don't think that much about it). Oddly enough, I can actually pinpoint a moment where she started doing it. It was the day before the Sault Ste. Marie excursion, and at 11:00 pm ish I went up the attic (where Cynthia/Cheryl/Maxime sleeps) to grab my sleeping bag plus other things...I didn't know she was sleeping so I turned on the light...and instantly she yelled at me (I don't blame her, I disturbed her in her sleep). But since then comments just fly out every now and then.
I don't mind when her criticism is true ("Your snoring kept me up all night") but when she seem to say things out of nowhere ("Yeah Angel sings quite a lot...it doesn't help she is off key")/("I find your view of the world to be limited") then I am just merely confused, because I don't know what her intentions are. One would think I am pissed off, but honestly I am more baffled as to what's going on and why she is behaving this way. I don't think I have pissed her off that she should start disliking me. If I must draw an analogy she is just like a mosquito that keeps flying around me...irritating but easy to deal with, nevertheless. My plan with her - I am going to wait a bit longer and see if her behaviour changes. If not I shall confront her, because who needs BS like this for another 7 months?

Second person - Stephanie. She is even harder to read because she never actually said anything mean to me (except for a couple of days ago where she and I are in the room alone and she told me I was snoring so loud last night that she almost had to wake me up, but that I could understand...man my snoring is a huge problem isn't it?) but I can feel her body language around me being different, especially compared to before. Again I really don't know what went wrong, and this one really could be my imagination...but I find my intuition for stuff like this to be pretty accurate. Again, I am going to observe the situation and if things are still weird I am going to talk to her...oh how convenient we both are house managers next week!

Really...if people have a problem with me they should just tell it to my face, rather than play mind games like this. Now why can't we all just get along?
