Help, can't tell if awake or asleep!

I keep having dreams where I can't tell if I'm awake or asleep. These normally occur after an event, a party for example or having a friend round. I will go to sleep as normal and then a few hours later think that the people from the party are in my bedroom or that the person who was round is STILL round. I believe that I sleep talk when this happens as I feel myself getting up and looking around for the people and trying to talk to them, only to find that they are not there. Am I awake or dreaming when this happens and what does this mean?

Keep a dream journal, and pay close attention to any recurring things you see over time in your dreams. By doing this, it will help you look for things your dreams in the future ("dream signs") that will be "red flags" that you are dreaming.

Pay attention in your everyday life, and try to discern the difference between your dreams and your everyday life. What is different between your dreams and your everyday life?
