It's helped me to think through certain things a lot more clearly than possible in reality...I know there's all this bullshit about "opening your mind" but in reality, it's something that RARELY can be achieved...for me at least, in the dream state, it's something that i can actually achieve, and when I reflect on some of the knowledge later, it adds a really interesting perspective that I normally would have never even stopped to consider. Definately led me to question a lot of things about what exactly is the "definition of reality." but yeah, overall I would say it HAS affected my personality (in a good way ).
