Phsyical, emotional, mental, what is next? I think I am pretty well aware that the physical body is influenced by emotions (blushing is an example, or a nervous feeling in the abdoment due to axienty). I think I am also pretty well aware the emotions is a product of the mental processes. When I take something for granted I am not thankfull and that is reflected in my emotions and physical body. During meditation I can put my focus on something which I would not call the sensations of the physical, nor are it my emotions and it aren't also thoughts. But, it influences all 3. Thoughts become more positive, I feel happier, and my body starts tingling with pleasant sensations.

I am reading about these different kinds of 'bodies'. The physical body, emotional body, lower/higher mental body, oversoul and spiritual body... I also read somewhere about the buddhic body. Now I am confused by all these different kinds of models/interpretations.

I've never read anything about distinct energy bodies from a buddhism perspective. The terms look so a like that it almost should be, but I do not find a direct relationship on the web. Does Buddhism support the buddhic body perspective? Is there literature or teaching related to this, or any other conceptualiziation of energetic bodies.
Briefly speaking, Mahayana and especially Vajrayana schools assign utmost importance to energetic phenomena at the level of latent potentials, hidden relationships, and subtle influences. However, we don't consider it a "body" or even any kind of bounded entity. We just say, the energy at that level is in flux, things are fluid, neither one nor apart.

If you think about it, in Buddhism we try to stay away from too much appropriation of stuff as me/mine. So recognizing energy-level phenomena but not identifying with them kinda makes sense.

Also it should be noted, that in (Mahayana) Buddhism we don't say that stuff on different levels is made from different materials, no. Physical, emotional, energetic, karmic - they are all here, made from the same stuff, but can be observed by focusing on different levels, from coarse to subtle, and these different observations produce different perceived planes (dhatu). It is very important to understand that all these levels or planes are same stuff.

To consider physical and spiritual to be two different things would be a gross error of Dualism, in Mahayana Buddhism.
