If you dream of a burrow or tunnel, it may symbolize deception and betrayal. Seeing someone digging a burrow for another person suggests that you might be deceiving that individual. Entering a burrow could indicate that you are confronting hidden information or truths, which may lead to some problems or complications in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Burrow" (page 62) â resolved via the equivalent "Tunnel" entry.
In a dream, a tunnel represents trickery and deception. Ifone sees himself digging a tunnel or a hole for someone else in a dream, it means tricking and deceiving him. If one enters the tunnel that he dug in the dream, it means that he will fall in his own trap. Ifone enters a tunnel or a burrow and cannot see light at the end of it, or if a traveller digs a hole, enters it and can longer see the skies or the stars above him in the dream, it means that thieves will rob him from his luggage, or that he will be high jacked, or stopped by a band of highway robbers. If one sees himself taking an ablution or a bath inside the tunnel or in the hole in a dream, it means that he will arrest the robbers and recover his property. Ifone enters a tunnel and takes a bath inside it in a dream, it means that he will pay his debts, or repent for his sins, or ifhe is incarcerated, it means that he will be released. Ifone digs a tunnel and draws water from it or discovers a hole filled with still water inside it in a dream, it means that he earns his livelihood from trickery and deception.
