Dreams !!

Before I found out I was expecting my DS I had a strange dream about fish , in the ocean . Throughout my pregnancy I would dream about the waves in the ocean . I've read where this represents the growth of the placenta . Before I got pregnant I didn't acknowledge my dreams but now i pay VERY close attention to my dreams . Before AF arrives I will dream about water (that's DH is drowning me ) very odd , I know . Within the next 24 hours AF arrives . I do not get PMS so that's the only way I know AF is fixing to show because as a result of BF I have a irregular period still . We'll the other day I had a dream about crystal clear water . Me and my family were traveling by water to some unknown destination  . Somehow on the way my DH got left and it was just me and DS . He was in an infant float and I was holding on to the side of his float . There were a ton of pretty yellow and blue fish all around us . They were putting on a show for us . Waves kept splashing up in my sons face , that's one if the most vivid parts that I can remember . AF isn't due any time soon .. So idk what to make out of this dream . I'm hoping maybe we have a baby on the way .. Then last night i had another strange dream DH was talking to me about our new baby . Then all of a sudden I'm standing in a field at dusk . There was a tree , and the sunlight was glimmering through the branches  under the tree was an angel . I'm not sure why I assume it was an angel .. It didn't resemble anything human ! It was flowing a Brassy color yellow . I've never had a dream like this ! I can't find much information on angels appearing in dreams . Does anyone know how to interput dreams ?
