Is Meredith dead??

Holy Shit! I just watched tonight's episode of Grey's Anatomy. Could they have possibly killed off Meredith Grey?
I'm assuming that she'll live since after all she is the Grey of Grey's Anatomy, but you never know. Last season, I was so happy that Denny Duquette survived his heart transplant and was on the road to recovery and then they up and killed him leaving poor Izzy laying next to his dead body.
Tonight's ending was such a surprise! Meredith flatlined and the Chief said, "We're losing her." Then the very next scene shows her waking up coughing looking pretty healthy. For a second I thought it was one of those dream sequences like when Bobby Ewing woke up on Dallas, or when the autistic boy in St. Elsewhere dreamed up the entire show while watching snow fall in a snow globe. This one doesn't appear to be a dream though since she wakes up and in her room is the very dead cute guy that got blown up last season and poor dead Denny. She asked "Am I.....dead?" and Denny said, "Damn right, you are."
I'm hoping that she's just having one of those medical near death experiences where you head towards the bright white light and see dead people, before you're sucked back into your broken body. I can't wait until next week!!
