Dose - THC overdose?

[integer]

last night i was smoking ice2000, i had about 5 joints but i wasn't as
high as i wanted to be so i filled up my pipe and went to work on it





after about 10 minutes of some huge ass tokes from the pipe i obtained
the greatest high i've ever had on weed, and then it just kept going
deeper and deeper. i had previous experience with intense shroom trips
so i wasn't freaking out that badly, but i had a number of crazy
effects that i'm a bit scared about. can someone please help me make
sense of this!





1. i had the absurd amounts of "brain pressure", it felt like my head would explode any second and that my ears were bleeding.





2. i would feel the internals of my brain, i could feel blood flowing
through my brain and all these warm waves of nothingness washing over
my entire body and especially my brain.

it felt very very wrong. its almost like i could feel every
particle of blood moving through my brain. why did this happen?





3. 1 weird effect was that it felt like i had multiple personalities,
whenever i thought of something i would hear like 3 or 4 answers coming
from my mind in slightly different voices and they all talked at the
same time. i thought i was going mental!
