You think that people do not treat you seriously enough and feel that you could be afforded a little bit more respect. The birthday is a period in which someone with even the worst track record and the worst morals will be rewarded for simply having been born. Even if you are absolutely horrible, there is a good chance that at least someone will come by to celebrate with you merely out of obligation. But chances are you are not a bad person. You are an average Joe who just wants to be noticed a little bit more. If this sounds like it applies to you then by all means, please revel in the birthday in your dreams. But if you really want to get noticed in real life, the best strategy is simply to be more outstanding, Make an effort to really separate yourself and what makes you special from everyone else. This will ensure that you will get some of the respect that you deserve.
If you dream that you are at the birthday party of another person, then do your best to recall who that person was. Are they someone that you are familiar with? If so, then this is a person that you think you need to afford more respect to in life. You want to let them know your true feelings about them and want to relay to them the fact that you think they deserve a little better than what society has been handing out so far. Make sure to make a special effort to show this person more respect when you encounter them in real life situations. This is important for both of you and you could learn something from it while teaching them something in the process.
If you dream that you are at a birthday party for someone that you do not know, then this suggest feelings of alienation and unfamiliarity. All of the guests at the party are gathered to honor someone that you have no connection with and for some reason you are there communing with them even though you do not know them, they do not know you, and most importantly, the person having the birthday party has no idea who you are. This means you are struggling with these same kinds of feelings in waking life. You need to make a little bit of an effort go outside your comfort zone and meet people that you think will be good friends for you. Basically, you just need to collapse the bubble that you’ve built around yourself after all this time that you’ve been using to keep other people out. What is the worst that could happen? You make a few friends in the process? Doesn’t actually sound so bad does it?
