A Magical Light Experience with a Few Real-Life Located in Lakewood, California, Imaginarium transforms what used to be a Forever 21 into a massive indoor light experience and honestly, the creativity alone is impressive. From the moment you walk in, it feels like stepping into a glowing dream. There’s a room filled with twinkling sunflowers. An immersive balloon space where hundreds of balloons swirl around you (imagine standing in a shower of balloons without them popping).
