Is Nothing Possible?

every once in a while throughout my 18 short years on this earth, probably about 5 or 6 times a year, while in deep thought I suddenly get an instant of imagining the NOTHING that i believe you are referring to, and it brings out the best feeling I've ever experienced so I hope that it is possible...I suppose that death is essentially this..so I'll finally get to experience that thought forever without having to suddenly be forcefully thrown back into a realization of the true world again...What a way to go out.
