An adorable family of five and their pet dog had a lovely moment sitting on a swinging bench, trying to capture the perfect family photo. The weather was so warm for fall that they were still able to wear tank tops and t-shirts. Little did they know that this innocent snapshot would send chills down the spines of those who take a closer look.

If you have already noticed the eerie detail, then I bet you felt goosebumps creeping up your skin. In the photo, pay attention to the girl on the left. There’s something on her arm that shouldn’t be there.
