Walking through Memories

Have you ever felt as if everything was so familiar yet so foreign at the same time? I took a walk last night through a place I found strangely familiar. There was this nostalgic feeling that was almost too overbearing. I couldn't explain why, but with every step I took. Every step that connected to the ground, I felt my heart go "thud" too... I looked around to find something to connect to my memories but I couldn't. Some things seem to have changed. People seem to come and go in that bustling place. I just sautered my way through the massive crowd, floating through them as if I was invisible. Just like a memory that was misplaced somewhere. I wondered to myself, is it real or just a dream? How long has it been? It was all just too real to be a memory I guess.
