Are these signs of a past life?

Hello, this is my first post here, and I am not so familiar with the topic of past lives, even though I have been interested in the topic of afterlife and reality.

So I have been getting this overwhelming sense of nostalgia, so strong that it makes me somehow sad/nervous. Where I have gotten the nostalgia from is basically early 2000 or even the end years of 90's products, media and pictures. But not only that, but specifically Japanese media, products and pictures. I have some images in my mind also, of what the place looks like, and the closest thing I have found that is close to my imagination, is some beach/coast areas in Okinawa , Japan.

I have always been interested in Japanese culture and media, so I don't want this to sound weird, it could be somewhere else too, but since the nostalgia comes from Japanese media, I thought it could be there, the place where the current me has never been, but I feel nostalgic towards. It honestly could be somewhere else in East Asia, I think.

The area is close, like right next to a beach. A coast/beach city, I think. The atmosphere is warm, and there are a lot of apartment buildings. White apartment building is one that is super nostalgic to me.

I don't know what to make of it. I was born in 2003 ( can my potential past live be so close/overlap my current life? ), and I live in Finland. So not in a warm area at all, and there isn't ocean close to me. And the nostalgic images I have, I am in early 20's in those.

What do you guys think?
