Dreams/Reality

I have been having a weird time as of late with this. Sometimes I wonder if something I dreamed actually happened and vice versa. I know this happens to everyone but as of late it has been happening to me quite a bit. I think it has been heightened by the cocktail of substances I am on on a daily basis (nothing harmful except maybe some alcohol and occasional cigs). I've also been thinking that it's a great idea to do paintings on the walls in my apartment when I'm drunk. I didn't dream about that. It actually happened.
