What does this dream means? And also should I tell my parents about this?

If you feel comfortable telling your parents about it, then why not....I think that is part of the reason you had the dream, because you are scared to say what you feel and the dream was saying to say what you feel. I think you are at the age where you have a desire to learn about love and romance but your parents probably have been telling you half the story when it comes to boys and you know its more to it than what they have been saying. I think that you believe what you feel wont matter to your parents so you keep all your feelings bottled up inside and you now you need to release them. : )
