Normal thoughts/No fantasies??

This may be a weird question, but has anyone else actually been a little scared to live without the fantasies and obsessions of dp/dr? I was thinking the other day that I don't even know what a normal thought process was (although I think i do, subconciously) so i keep questioning whether my thought process IS normal. The oddest thing is that sometimes I'll feel connected, or my mind will be at peace, and it freaks me out a bit, because then i wonder if I am then going brain dead or have had an aneurysm burst or something in my head. Is this at all normal (at least in these circumstances), or am I just a freak (well, a freak in this regard :shock? It kind of makes me think of the Alanis Morissette song (groan, i know, but i like her)
"these precious illusions in my head did not let me down
when I was defenseless
and parting with them is like parting with invisible best friends

these precious illusions in my head did not let me down when I was a kid
and parting with them is like parting with a childhood best friend"

It's like I've had them so long, and they are so unhealthy, but they are like friends to me now, you know...bad friends, but friends nonethless.
