Cant see when I project, and also a question about awareness.

Recently I have been having problems of getting my head out of my body, today as I had the vibrations and then felt myself leave I imagined in my head my body leaving whilst having a positive attitude, and I imagine my head leaving my body, my main focus was just me visualizing my head doing this, and eventually it detached and my astral body leaned up from a position of lying on my back , and I also felt the spirits or whatever they are hold my hands as I left, about two or three maybe four I remember glimpsing, as I fully detached I just began floating around in my room, and I could not see, I only had less than a few seconds of sight, but the rest was just black, I could feel, and had a few moments of hearing, but I have had been having problems of mainly not seeing anything, now my question about my awareness when I project is, when I project my awareness there is usually the same as how aware I am at the time when I am back here, and as I am usually in quite a deep state then, but I still know what is happening, today I was able to have a little bit of control over my body which I have struggled with recently, but how great can your awareness be when you project? What can I do to increase it? I have only had tasters of how great my awareness can be when I project, but have not yet had a full experience with that level of awareness yet, I would like your help on both questions, thanks :)
