Not exactly. Can reality appear in dreams? Perhaps. Can dreams come true in reality? Not exactly. Usually, it can just be simple forms of Deja Vu. Other times, it's going to be what you've wished for or hoped for to the point where if something even remotely similar to your dreams happens, you're going to instantly come to the conclusion that your dreams have come true. Everything that's going to happen in your life is always affected by the things you have already done in your life during the past. If you kicked a cat when you were five, and then later when you were ten you had this descriptive dream on how you have always wanted a cat or maybe it was a literal dream and you dreamed of owning a cat? However, let's say, you're broke? Then, maybe come two weeks later and you see a stray cat and it takes a liking to you; you receiving a cat. It would be a mere coincidence. Maybe it came from the ancestry of the cat you kicked years ago? So, it stayed abroad as a stray or something? most of the cases of dreams coming true are usually just our brain's misinterpretation on reality, or maybe it's all coincidental. I didn't really understand the question, but this could help to some extent?
