Any practice that causes: hallucinations, shaking and tremble, nausea, diarrhea, headaches, etc. doesn´t agree with the suttas and probably wasn´t taught by the Buddha.
Well, of course, those are listed under "imperfections" or "corruptions of insight" in the texts...
The development of mindfulness and concentration can have all kinds of side-effects. Uplifting ones (bright light, feeling of floating) and more disconcerting ones (shaking, and so on). Many of these are not really specific to Buddhist practice...
Some of these are hinted at in the suttas. Mostly positive ones, for example, here:

There are also suttas that talk about arising of fear, and so on, and what to do about it.
Any practice that aims to make significant changes to one's mind, and one's life, is likely to have side-effects. Some good, some not so good. I think it would be naive to go into these practices thinking that progress will always be easy and pleasant.
