Seeing bizarre things in you dreams it not unusual. Dreaming is often a psychedelic journey, completely disconnected from reality. A world where anything can happen. A world where your unconscious can use almost anything to try to get a message to you. Squids are frequent players in these dreams. You might wake up from a dream like this and wonder, "What does it mean when I see squids in my dreams?". The answer to that question differs depending on whether you are simply seeing squid or eating them.
If you see squid in your dreams it could have two different meanings. The first is that your unconscious mind is trying to tell you that you are not seeing things clearly. Perhaps you are feeling threatened and it is skewing your judgment. The other possibility is that you unconscious is trying to tell you that you are being somehow self-absorbed or greedy.
If in your dream you are eating squid then that has a different meaning. This implications that you are overly concerned with how other people see you. Something may have happened recently to make you feel very self conscious. Now you are spending too much of you mental energy worrying about others opinions of you.
Often what happens in dreams is the result of your unconscious trying to get your attention. It can sometimes be difficult to interpret what you unconscious is telling you. Dreams that involve squids can mean a few different things, but they all refer back to how you interact with the rest of the world. Seeing squid in your dreams means that it is time for you to take some time for yourself and figure out which of these issues you are currently dealing with and take steps to fix it.
