Do i have insomnia

first of all i have anxiety disorder,which i am treating.I dont know if it is all in my head but i feel like i dont sleep or i dont sleep very good.You know the disease Fatal Familial Insomnia that chills me to the bone,but anyway i wanted to ask,if you dream does that mean you sleep okay,does that mean i have passed all other sleep stages and i am in rem sleep

A lot of people mistakenly think they didn't get much sleep when they got enough. The human body will make you sleep when it is tired enough and everything else is usually just in your head or your anxiety playing tricks on you.

As for FFI it only occurs in certain families so unless you have a family history of the disease I wouldn't worry about it. The sporadic one can occur in anyone, but there have only ever been 8 documented cases of it ever meaning that it is one of the rarest diseases known to man, also I wouldn't worry about it.
