For me...
Falling in love is like
Driving into a dark tunnel with no headlights
Biking down a steep hill without a helmet
Jumping into deep water before learning how to swim
But it's also
Hearing the beat of the car radio bouncing off the walls, echoing throughout the tunnel, and feeling completely engulfed by the music
Riding down so fast that you feel like you're floating and as the wind kisses your face, your heart pumps with adrenaline.
The moment underwater where all is quiet, the world has faded away, and you feel completely at peace
