Yeah, i state in another comment
The reasons i use to think it was placebo, because when i listened to a field and read reviews, i would see this field makes me happy, and i would be like yeah am happy right now, then when i read another comment that said this field makes me feel dull,
I would be like i noticed that right now, am feeling dull. and so i would think its placebo as am creating the sensations.
I dont think that gave u the right answer, but just some context of where am coming from
