Is enlightenment an early death?

I had a spontaneous "awakening" a few days ago and it really scared me, to the point where I'm still wondering if I'm sane. I can't not see my family as separate entities anymore, as natural as the wind and the trees. I can't not see my thoughts as impermanent. There's a hollow sense of being all alone in this timeless existence. I just want to forget and go back to normal. It's scary.
