I love dreams and have since I was a child. I keep a dream journal and regularly record my impressions. However if you really hate the kinds of dreams that are given to you then I would recommend smoking some weed before bed. Doing this for a little while should completely halt your dreams. The only downside is that you will get a worse quality of sleep overall. I suppose you need to weigh each issue against the other to see which would cause you more distress; to continue having disruptive dreams or to have a worse overall uninterrupted quality of sleep.
