I'm so sorry you had such a reaction as well....But at least now I know it was (almost certainly) the valerian that brought it on, even though it is herbal and seemingly harmless. Maybe we have hyperactive imagination - this demon "it" isn't new to me, I've had similar dream-terrors (nightmares is too meagre a word) with antipsychotics and I've had fairly crazy dreams since I was a kid.

Anyway, I think I preferred a lot more my 4 hrs sleep last night than the valerian effect!
