An obstacle in a dream typically signifies the missteps that would take place in the real world if left unchecked. Be more attentive in your waking hours to avoid any missteps.
Also, the obstacle in a dream often represents a fear or something we feel is standing in our way of achieving a goal. Many times, with the help of friends and peers, we will be able to overcome these obstacles easily.
Sometimes, the paradox is that to overcome the dream’s obstacle, the dreamer has to rely on the power within themselves for support and understanding.
