Body jumping symptoms and conditions

I have been taking Effexor XR for a year now. When I first started I was taking a 150MG now I am down to 75mg a day. I have experienced a lot of abnormal dreams and usually I am interacting in my dreams. I also have experienced different parts of my body jumping. I am coming off of this medications and work on my anxiety on my own. It is always best to do everything natural because no one knows what medication actually does to your body but I can tell you I have had some strange feelings.
