Well you have some interesting dreams,but then again I think we all do.As for your question about if it's related to astral projection,my best guess is no.From what I have read about astral projection is that you have to conciously leave your body from either sleep paralysis or a meditative state.Im not sure if that's fact because I have never had an astral experience.It sounds more like you had a false awakening which is when you "wake up"in bed in the dream,yet your stil dreaming.A good way to counter this is to get in the habbit of reality checking when you wake up.I rarely have fasle awakening,but when I do I was either already lucid or it got me in a position to get lucid.You sound like you're really close to getting lucid so don't stop now.
