Vivid dreams

I know you aren't pregnant until after implantation. I was wondering if anyone had very vivid dreams after <a href="https://glowing.com/glow-fertility-program">iui</a>? Im only 4dpiui but my dreams have been consistently SO alive since the <a href="https://glowing.com/glow-fertility-program">iui</a>. It's literally like a real life movie, I have even jolted awake a couple times. Anyone experience this? What could cause this? Just a weird coincidence since started right after the <a href="https://glowing.com/glow-fertility-program">iui</a>.
