For kids with sensory processing disorder (SPD) or anxiety, the sights, sounds, and spooks of Halloween can be completely overwhelming. Decorations like strobe lights, automatic mechanical props, fog machines, and anything generally scary or creepy can be enough to trigger someone that struggles with sensory sensitivities or anxiety. Strobe lights and mechanical props can be especially triggering for epileptics. Personal space is also very important. For those with general sensory disorder or SPD, everything they experience is louder, brighter, bigger, and closer to them.
