I think the earliest thing i can remember was when I was about three or four years old and i opened my pantry and it was literally completely full of chef boyardee. This is a pretty exciting thing which is why i think i remember it so vividly, but the only problem is that im pretty sure that it never happened and in fact i've never even eaten chef boyardee before so I'm pretty sure this was fabricated by my young mind.
I am absolutely not the same person i was then considering the huge intellectual gains i've seen in the past 4 or 5 years. The importance of these improvements being that they have changed my personality pretty drastically.
Sometimes this happens to me too. I often think back on memories that I cannot differentiate whether they were real dreams or actual memories. This event of yours may have happened in a remembered dream that was so vivid to your young mind that you took it as a true memory.
