Recurring dream

Recently ive been having a recurring dream where i can stretch my limbs there is always another person with me but i never know their identity. anyway it started off this time where i was swimming in the water and this person whose identity is unknown came up to me and spoke to me i realized it was a female, we started talking and i asked her if she was this girl i knew. but i was wrong and she got mad and ran away. after that for some reason i was up on a mountain throwing my arms down to the beach but they would stretch about half way if i threw my arm with all my might but wouldnt completely reach. after this happened i called a friend of mine and found out the mystery girl from before was with her and she was mad i didnt know who she was. then i woke up... usually i ignore my dreams but this is one of the only dreams ive had more than once.. it was so vivid it felt like it was reality.

anyway if anyone knows anything about dreams like this thanks for the info
