neg or not

[Adkha]

Hi, a few nights ago I had this weird nightmare I would like to share with you all.

It began just nice, with some kind of party with friends and unknown people. But all of a sudden we heard screaming, so we checked it out.
We saw a guy standing with darts in his chest. IT was horrible to see. He was in very much pain. Then we saw who was throwing these darts. IT was a really weird human like person. He had a normal body and face but the look in his eyes was very scary and weird. He took all the time to throw these darts. Then he saw us. And he began to throw at us. One of us got hit and me and some others got behind a car.
Now comes the nice things of my nightmares. I always realize that I am dreaming when these nightmares occur. Sometimes I just wake up. But most of the times I keep on dreaming and I can laugh the killer in the face and make hum disappear.
BUT this time I was still a bit scared. I was afraid he could still hurt me. And them I woke up

Could this be a neg?

Another question...can anybody give me a good tip to stay lucid for a longer period? I always wake up quickly after I realize I'm dreaming
