I've been having problems sorting out what is reality and what is not lately. My dreams always seem so real and I usually think they really happened until a while (days, more or less) later I find a flaw with the logic or figure out that something really didn't happen. I'm glad I eventually sort out that something is not real, but sometimes it scares me that I think it is real for so long. Has this happened to anyone? Does anyone know if there is anything I can do about it?
