People often have strange dreams about creatures that can be interpreted in many ways. Some people see monsters or aliens, while others might see deceased loved ones. For some, it can be a subconscious reaction to stress or anxiety.
When we wake up from a dream about a creature that leaves us with bad feelings then it may indicate that we made mistakes or missed important signs leading us to fear and failure.
Caught by a monster in a dream means that there may be some danger in us or our surroundings. Sometimes it can also mean that we have been caught because someone is trying to take revenge on us for things we did that we are not too proud of.
