Migraines and Altered levels of Consciousness

So i'm just wondering what others think about Migraine and Consciousness?

i suffer with what i describe as extreme migraines which put me into what i feel is an altered state of consciousness. My brain function is not the same as it was prior to the migraine, i cannot think straight, i am unable to interpret things in the normal way, my vision is not always 100%, my hearing is altered, all my senses can be effected, smell, touch, taste, communication.

I've seen a thread on this forum about Migraine and Nightmares which talks about migraines in your sleep and dreams, i experience a real living nightmare when i have a bad migraine and it feels like a dream/nightmare but i am most certainly awake, it happens while im lying down in bed in severe pain, i'm not quite sure whats going on but i often feel like im on a rollercoaster from hell quite literally. I feel like im in another world or place, my level of consciousness is not the same as it was before the migraine, i am experiencing an altered state of consciousness i beleive. I feel disorientated my thinking is impaired and my responses are much slower than they would usually be, i also feel extremely restless and agitated and i lie in bed often mumbling or groaning in pain often squirming with each wave of pain that comes trying to twist and turn to find a position that might make me feel better but each time i move the pain usually gets worse, i really feel like im in another place or world while this is happening, somewhere very dark, i think the whole situation becomes a real nigntmare as it's something you know you cannot escape and the level of pain is undescribable, being tortured is the only thing that comes close. I guess your imagination might play a part, when you close your eyes when your in pain i can't imagine your going to see anything nice but it sure feels to me like im experiencing an altered state of consciouness.

I wonder if others here have similar experiences?

i also wonder if it's commonly accepted that migraines put you in an altered state of consciousness?
