me and my sister were at a fair or some kind of park
It seems like your sister could be a recurring dream element, given your other dream from last month. If you see her IRL, or do something related to her, try doing some reality checks and pay attention to your surroundings to see if anything is strange. Hopefully your reality check habit will apply to your next dream featuring your sister For dream recall, try taking a dream fragment like this, and backtrack to find other dream fragments you can use. Keep your eyes closed when you wake up, and think of nothing but the fragments you can remember, and piece them together to form something more detailed. However, we all get bad days where we can only get small snippets no matter how hard we try. The more you flex your brain to remember things, the more effective your dream journal will be at improving your recall. Eventually, you'll be able to easily remember 5 vivid dreams in one morning Good luck!
