Nonono! I remember many good dreams! Actually I remember a dream I had just two weeks ago now that I think of it. I dreamt I was talking with Marisa, it felt so real that when the alarm on my phone sounded I actually thought it was me chatting with her on the forums, via my phone somehow. I put my alarm on snooze over eight times. >_<
But I remember nightmares from when I was a four year old... Maybe your right... D:
