>Be around 10 y/o
>Playing out back with my friend
>He's like 13 at the time
>We are on our Razor scooters having a blast
>Have an idea
>Want to make a figure-8 for some dumb kid reasons 
>Make pic related figure-8 with the scooters on my parents driveway for no real reason other than for fun
>My friend is the red line, he went around in circles (his direction could have been reversed but I believe it was counterclockwise)
>I was the blue line

Before I continue I want to add that directly below the picture (so this would be the bottom of the square in pic related) there was an alley. Across the alley there were around 4-5 boys from next door playing basketball. They were close to our age. (1/2)

 >We start to do the figure-8
>The boys across the alley are being loud and yelling (normal kid stuff)
>As I (the blue line) make my final circle in the figure-8 I see one of the boys shoot the basketball
>When I hit the middle of the figure-8 I stop (now facing up on op pic related, toward the garage)
>My friend stops as well on the right side of pic related just at the edge of the square
>Waiting to hear the basketball drop from the hoop
>Hear nothing
>Turn around
>The kids across the street are gone
>The whole block is very quiet
>I turn to my friend and ask him if I'm retarded or if there were kids playing basketball literally 5 seconds ago
>He turns around and starts freaking out when he realizes they're gone
>We both question our sanity and are genuinely shocked. Neither of us have experienced this before.
>Talk for a couple of minutes making sure we knew FOR SURE that the guys next door were playing hoops
>Feel so shaken that we go next door and knock
>The kids mom answers
>'Hey, weird question, but were the boys outside playing basketball a few minutes ago?'
>She responds: 'Oh they left like 30-45 minutes ago, they went to the corner store.'
>My buddy and I are completely dumbfounded

To this day we still don't understand what happened and both vividly remember the experience as written above. Does anyone have any idea what we might have experienced? It's the only 'paranormal' experience I've ever had. Did we switch dimensions or something? Abducted by aliens? Gas leak or something? I'm not sure why but I'm suddenly compelled to solve this mystery as an adult. (2/2)
