What Does This Dream Mean?

On the 2nd day of January 2018, precisely around 2:00am: I woke up scared like a baby locked in a very dark room all alone. I have had terrible nightmares that do not even move me a bit. I have had bad dreams that I even wake up sweating, I still don't get worried over them. This one really got me because until I woke up, it looked real that waking up was more like a way of escape that gives someone a sigh of relief. I dreamt that I was dead.... The dream didn't show how it happened, I only saw that I was doing everything normally but no one could see me, feel or touch me. In the dream I saw my wife and relatives and I felt bad for them. I saw that I was talking with my mother but she couldn't touch me and I was saying in my heart: "this woman doesn't know that I'm no more with her" In that dream, I was saying to myself; "God if I'm to return to life, I want to be very wealthy" (actually, that's the only part of the dream I liked.) I've never experienced such, I mean I woke up almost peeing in my shorts. I started pleading the blood of Jesus, I started quoting scriptures, in fact I started speaking in tongues. I immediately jumped to Google to find out what it means to dream that you're dead but I never really got any convincing result. Before I ask those of you who could interprete dreams to start telling me what that means, I will like you to know that the dream also reminded me of the fact that no matter how long we hope to be here, our stay here is only for a while. The moment you drop dead, you've lost everything, you've left it all behind. In a way it was a kind of signal for me to work towards a new me. It's time to live like the next moment isn't mine. All that said, I am not ready to die yet and I won't, Let me ask Dream interpreters... please what does it mean to have such dream?
