Weird dream - I'm invisible, but noticable?

[kidkurious]

In this dream:

I die in a car accident (car racing) - While I'm driving, I close my eyes thinking I'm going to crash. I hear somebody say "open your eyes!"
I open my eyes and I see myself in the spectator crowd reaching for something.
The thing is, when I see myself in the crowd, it isn't me, but somebody else, but I know it's me.
When I die, I see myself dying.
I go back to my own point of view.

Now, on the race track, I'm a ghost - I'm standing and I'm looking down at the floor. My head is bleeding, dripping with a lot of blood form the back of my head. It doesn't hurt, but it feels wet and I can feel the blood pouring out of my head. My nose seems to be bleeding a bit too, so I blow my nose, but it doesn't help. A girl in front of me says "that's not going to help". I blow my nose at the girl and some of my blood shoots at her face, but she doesn't seem to be bothered by it.

Next, I'm still a ghost, or so I think. I seem to be invisible, but my shadow seems to be visible at times. Somebody (from my school) seems to notice me (he can't see me, but he knows I'm there), and calls me "fat". Then, I playfully hit him back but I miss as he runs aways. This happens several times (in real life, I'm not fat at all. I workout and I'm in good shape).

My cousins are over at my house and they can't seem to find me (because I'm invisible). My shadow appears on the floor several times, though I am still invisible.

I end up in my backyard.
I'm still invisible, but I can see myself in the reflection of a window.
In the reflection, I see myself wearing a tie and a fancy vest.
Wind starts to blow against me.
I start punching against the wind (boxing).
I think to myself when I'm doing with punching against the wind, I will be stronger when I come back to life.

Next, I go down to my basement.
I come back upstairs and the whole invisibility/ghost thing makes sense to me. It logically doesn't make sense, but I can feel that things are right.
With this feeling, I am visible and noticeable again.
I feel a sense of relief that I am visible again.

What could all this mean?
