I have chronic insomnia, I can go up to ten days without sleep, but after about three or four days I start dreaming while I'm awake, and as I get further with no sleep the dream stages get worse and longer. For example, as of 3am, I will have not slept for five days, but I had a very horrific nightmare (featuring chainsaws) about twenty minutes ago... The cause of my insomnia is still unknown, but I have also been slipping in and out of being underweight (I'm currently 90lbs and 5 foot 5.) Can anybody help me with any of this? Thanks
