What is your earliest childhood memory?

This morning I was having a flashback to when I was about four years old. I distinctly remember a cold leather chair in a dark office only illuminated by computer monitors. I vaguely remember an elderly white haired doctor who shook my hand and mumbled a bit. My mother was sitting in the chair across from me smiling. The next part is what freaked me out a bit. The doctor comes in and tells me to stay calm and don't worry. He then begins to stick some sort of electrodes along my skull (something like this). He then starts up one of the displays and writes on a clipboard. Then my heart started racing, and I ripped all the little electrodes off my head and ran out of the office, with the doctor and my mother chasing me. I don't recall much after that. It may not be significant to you, but it felt like something out of a science fiction film.

So reddit, what is your earliest memory?
