To get started, you'll need to open Google Maps, not Apple Maps. You can access Google Maps on a computer or via the Google Maps app on your phone. If you're on a computer, visit www.google.com/maps. If you're on your phone, download and install the Google Maps app (Android or iOS) if you haven't done so.

Once you're in Google Maps, locate the search bar at the top of the screen in both the app and your web browser. Type in an address -- whether it's your house, your grandma's house, or any other location -- and press Enter or tap the search icon. Google Maps will zoom in on the specified location. You'll see an overhead (satellite) view at first, but don't worry, as you'll be switching to Street View in the next step.

Look for the small yellow figure (often called "Pegman") in the lower-right corner of the screen. You can click and drag Pegman onto the street to enter Street View. Alternatively, on some devices, you may see a small photo thumbnail or a "Street View" button directly below your address. Tap on this to enter Street View mode. In Street View, you'll see a 360-degree, street-level view of the surrounding area.

Here's where you can start to stroll down memory lane. In your web browser, look for a small clock icon or the words "See more dates" in the top-left corner of the Street View screen. On a mobile device, this option will appear at the bottom of the screen. If you don't see it right away, try tapping on the Street View or along the street by tapping the left or right arrows. This can trigger the "See more dates" option to appear.

Once you spot "See more dates," click or tap on it. A timeline will pop up, showing you all the times Google's Street View car has driven by and captured images of the street. 

Each past view will be listed with a month and year (like "June 2012" or "October 2009"). Click on the specific date you want to revisit, and the image will change to show how the address looked at that time. You can click or scroll through the timeline to view all the available images.

This is the part where TikTok users are getting emotional. If you look at your home, you may spot younger versions of yourself, a beloved pet, or a loved one who is no longer with you. It all depends on who or what was outside when Google's cars passed by the house. If they've driven by multiple times over the years, you may see snapshots from 2007, 2012, 2017, and more.
