I wouldn't put any stock in dreams. The mind is a powerful thing, and when it's hyperfixated on something (such as having a baby) it stands to reason that you will begin to dream vividly about such things.
During the longest stretch of TTC (over 2 years) I had multiple dreams about pregnancy, but each cycle only bought a BFN. I had no dreams before my BFPs, but weirdly I kinda already knew I was going to see a second line.
With respect OP, I had a look at your posting history and a couple things stand out. The first is that this is now your 11th month of TTC, which certainly explains the hyperfixation. However, it taking up to a year is normal for 80-90% of couples under 40. It sucks to be in that 10-20%, but at least soon you can get the ball rolling on a fertility consult, in which time you may conceive anyway.
The second is that unless you haven't tested at all since your last period, you are not pregnant. If you were, then you would be 6-7 weeks, and there would be a definite line. As it is, you are 15 days from the start of your last period, which means you've likely only just ovulated, and sperm might not even have met egg yet.
Third is that you become overly aware of your body when TTC. As I said, the mind is a powerful thing, but it can also be tricked and convinced otherwise, which then leads the body into believing it is experiencing symptoms it isn't. Please try to relax, it really isn't healthy to obsess over this. I would know, I've been there. The stress might also be impacting your fertility, so it is absolutely for your benefit.
I genuinely hope this cycle will be the one for you.
