Yes. I would tend to agree. But it is interesting that Laura is deeply conflicted about her feelings towards Carmilla:
"Now the truth is, I felt rather unaccountably towards the beautiful
stranger. I did feel, as she said, "drawn towards her," but there was
also something of repulsion. In this ambiguous feeling, however, the
sense of attraction immensely prevailed. She interested and won me; she
was so beautiful and so indescribably engaging."
So perhaps there is a comment on the contradiction of feelings which are socially acceptable and those which are innate and spontaneous but deemed to be unacceptable.
