Caer Ibormeith is the Celtic Goddess of Dreams, Prophecy, and Sleep. She was the daughter of Ethal Anbuail of Sid Uamuin of the Tuatha de Dannan. One story about her was what she did each Samhain. She was a shapeshifter and would spend one year as a beautiful woman and then a year as a beautiful swan. She would change each Samhain. She was very independent, and she was stronger than her father. So each Samhain she would go to the lake of Dragon’s Mouth and change shape for the year.
Another story about Caer Ibormeith was a result of her independent ways. She was determined to be the one to decide who she would marry. She decided that she wanted to marry Aengus the Celtic God of Love, Youth, and Poetic Inspiration. So she started to appear in Aengus’s dreams. For a year Aengus dreamed of the mysterious woman, but each time he would reach for her she would disappear. Over time he didn’t want to do anything but sleep, where he would dream of Caer Ibormeith. But he did not know who she was, so he decided to look for her. He asked for help from his family, and with them all working to find her they soon discovered who her father was. Aengus then went to her father Ethal Anbuail to ask for her hand in marriage. Ethal told Aengus that he could not grant him such a favor. Because Caer Ibormeith was not one to do something she did not wish to do, and she was much more powerful than he was. But he also told Aengus how he might be able to win her out of her own free will. Aengus was told to go to the lake of the Dragon’s Mouth on Samhain. It was there that he would find Caer Ibormeith and her 150 handmaidens. He would need to be able to pick her out while she was in her swan form. He would need to be able to pick her out from her 150 handmaidens and call to her. Then she might go to him of her own free will. He looked at all of the swan’s swimming in the lake. As he looked at all of the swans he realized, they were all beautiful, and they all wore silver chains. He doubted he would be able to find Caer Ibormeith, but then he saw one swan that was different. This swan was wearing a silver and gold chain, and it was more beautiful and elegant than all of the rest. He then knew it was her and called to her. Caer Ibormeith slowly swam to him and then changed into her human form. Aengus asked her to be his wife. She replied with a single condition. She would marry him if she could return to the water. To answer her Aengus turned himself into a swan and joined her in the water. They swam together singing a beautiful song that put the townspeople to sleep for three days.
Caer Ibormeith proves a few things in her myths. She shows that she is a powerful and independent woman who goes after what she desires. She visits the man she loves in his dreams to the point that he comes to find her and prove his love. She is the Celtic Goddess of Dreams, Prophecy, and Sleep. She has also been called Shapely Yew Berry and Yew berry. I associate the colors of silver and gold to her because of the silver and gold chains her and her handmaidens wore. I also associate the color white to her because that is the color of swan she was. I also associate white feathers to her because of her being able to transform into a swan. I also associate water with her because she wished to be able to return to the water. I associate music and number three with her because they sang and the townspeople slept for three days. She is also associated with dreams since she went to Aengus through his dreams. She is also associated with swans, which are symbols of love, purity, the soul and music.
