Vivid Dreams?!?!?

My husband and I had sex on the first few days of me ovulating, and since then I've been having vivid dreams! Like they are so real. The first was I went to the doctors, and did a blood test. They told me,"you're pregnant." And we did a 4D ultrasound, and I saw the baby's face and little body. Second dream, I took a clear blue digital test and, it said,"pregnant". And the third dream (last night), my husband came home from and was laying with me. Like he was in the bed with me. But, he was at work. What does all this mean? Am I'm going crazy. I haven't had any vivid dreams like this before.
