Hi, I Experience Very Vivid Dreams On A Nightly Basis,

Hi, I experience very vivid dreams on a nightly basis, and I remember them every morning when I wake up. Some nights I have woken up my roommate because I was sobbing durning a nightmare. I feel like I never sleep because it's like my mind never stops. I also find it extremely hard to focus through the day and I am wondering if this is due to not sleeping well.
