Jack-O-Lanterns are associated with Halloween, The Day of the Dead, and All Hallows Eve. They symbolize spirits and protection. Seeing a Jack-O-Lantern in your dream could indicate that there is an area in your life where you feel the need for protection or security. Alternatively it could represent a desire to connect with loved ones who have crossed over. It could also indicate a desire to see beyond the veil of illusion and connect to the spirit world on a deeper level.
