Mindlessness

Okay, so I am pretty sure this all mental, but I have been suffering from some serious "out of body" experiences lately. It is like my head is not attached to my body and I am just mindlessly wondering around, forgettiing ALOT, doing things twice, having weird dreams, falling down or tripping for no reason and the list goes on. I am sorta blaming this on the fact that on Sunday, I am having a monumental day, a day of celebrating, I guess (although lately, not feeling like celebrating due to this weird phenomenon I am having), eating cake and other de-lishisness. I am turning the big 3-0. That's right. I am "offically old" as I used to tell my two sisters that have both turned 30 before me and now I am there. I can only imagine how they will tell me how "old" I am now. Bring out the black balloons or something..maybe that is just 40? Oh goodness, only 10 years away.
So, my question is, is this normal to be feeling so mindless or am I just crazy? (Chris is not aloud to answer.)
