Very vivid dreams symptom before BFP?

I am 6dpo today and the past 2 nights or when I’ve taken naps I’ve had very vivid dreams. So much so that when I wake up it’s always a shock & im confused where I am for a second. One dream I was taking OPK’s and it was clearly positive and my husband was like “that’s a pregnancy test”. Then in my dream last night I knew I was pregnant and that I was having a boy.

Anyone else have this before their BFP?
