Flying in the clouds

I am a 19 year old male, and I just started to become more spiritual and have just recently begun to delve into spirituality and God.

I had a very lucid dream last night, that I was flying horizontally (almost like superman) in the sky between the clouds. As I was flying in the air I gazed down and below me was a a beautiful scenery of a stream and green trees as far as "I and eye" could see! And I felt the beauty of the scenery and the serenity within my being; pure euphoria, but then all of sudden as I was still flying in between the clouds, I noticed there was a dark tunnel in front of me, right up in the same sky that I was flying in, and I was headed right for it! And I couldn't stop myself from flying! At first, I felt relaxed and thought no problem, God will save me from that tunnel, but I just kept getting closer and closer without any deliverance! The tunnel also seemed more and more "tight" the closer that I got. I finally started to panic, I feared greatly that I might get stuck in that dark tunnel! So I exerted myself to the fullest and I begged God to save me, and all of a sudden something lifted me up vertically and I soared up and just like in "jack and the beanstalk" I found myself above all the clouds and the realm I was in before in to a new realm of nothingness, and all of a sudden in a split second as soon as i entered that realm of nothingness a cloudy/liquidy looking white light appeared right in front of my eyes which made me wake up panting!

What does my dream mean?

PS: this was the most lucid dream i've ever had, all my other dreams are not clear (i.e. black and white) and seem to make no sense, like say dreaming of dumbo blowing up bubble gums...;)
