Almost a year ago today, I went on a date with this guy who I hooked up with, and it was our first outing together. The relationship wasn't anything offical, it was only a hookup that lasted about 2 weeks. And earlier today when I was taking a nap, I had a dream he invited me over to his house. When I first walked into his house, I was greated my his little sister, but he really doesn't have a little in real life, his 'sister' in my dream was about 10 years old. We were standing in their living room and it was complete empty of furniture because they were getting their carpet cleaned, then his 'sister' led me to his bed room and said, "He'll be here shortly, just wait a few minutes." Withing a second the 'sister' was gone, and he appeared and gave me a hug and looked me in the eyes and said, "I missed you so much." Then we started making out for a bit, and I woke up. But all the while the dream was going on, I was thinking to myself, 'why am I here?' and 'why am I making out with him?' when my dream self continued to go on with the dream.

What could this mean?

Also, I have only talked to this guy two or three times since we split.

when you meet people, date people whatever they have every opportunity to enter your dreams even years later i don't think this has any sort of meaning.
