Its more common then you think. I too get these dreams. Im not sure if it runs within my family but my mom and sister dont get them. Though my sister sees spirits so does my mom and I. My cousin also gets these dreams. I think everyone is capable of these dreams. These dreams are just one type of dreams that us humans have. Ill give you a list below.
False Awakening Dreams
If you dont have a dream journal is suggest you get one. They help alot. Also focus on your dreams and things that may help you dream more. Ive been healy interested in this area becaues I want to know what causes these dreams to occur, If you can control them as in making them happen more, Also it can be hard to distinguish normal dreams from prophetic sometimes this is also where the dream journal comes into hand.
Im not sure how old you are. But as I got older I realised that some of the dreams I had that where prophetic didnt come true the way they where presented in my dream. You will notice this as well. Dont get freaked out. This happens becaues we humans have free will, Also things change all the time in our lives. So for example I had a dream me an friend where drinking in my friends apartment in a part of town known for violence. In my dream we where all drinking and someone smashed down her door and broke in . I wrote this down in my journal. I got a call from a friend saying she found a new apartment around 10 months later. We where all drinking celebrating an congradulating her and BAM. I had a dejavu moment. My brain felt like someone switched on the dream I had months prior an what happend. I didnt tell anyone an just waited for someone to break down the door. But nothing happend that way at all thank god.
If you dont mind me asking how often do you get these dreams? do you do anything special before bed? rituals, burning incense or herbs? drink a certain tea? pray before bed?
