I'm asked about dreams all the time. I'm probably the wrong person to ask! Lol... Just being honest. I'm not a Psychologist or anything, definitely can't be defined as 'normal'. I can't speak to anyone elses' dreams but I can give you my thoughts on my own.
Mine are weird and sweet, sometimes crazy, really. My mind is always going a mile a minute during the day. It's no shock that it would do the same in my sleep. My dreams tell me when to check on old friends, when to maybe give a new friendship a chance-when my friends or family needs me. When I'm stressed & practically a hot mess or lost- I'm visited by those in my past who have passed on to remind me life is short. Life is meant to be enjoyed. Sometimes my dreams are just funny gibberish or ideas for my next book that I won't ever publish, lol! You know those dreams you wake up laughing at? It's a friendly way of getting me to take a breather, that I'm doing too much.
Other times your dreams are a direct reflection to what's going on in your life at the moment. If they are scary or anxious dreams- try and not watch any creepy movies before bed, try prayer or peaceful meditation before surrendering to sleep, think of positive things before sleeping, and definitely avoid scrolling through your cell phone late at night. The internet is worse than some horror flicks. Just a few recommendations. There's often a simple anwer to changes in your sleeping patterns or dreams. Don't be afraid of your dreams- it's the equivalent of being afraid of yourself! They say everyone represented in your dreams are people you've seen before at some point that your mind subconsciously remembers. Maybe someone you passed on the street at some point in your life. The mind is amazingly complex.
If you're an intuitive, like me, you'll realize no dream is a coincidence. They all mean something if you take the time to think on them. However, just remember, living your life is about enjoying it and being happy in the present. The point of life is to help others and living your best life. Stressing about your dreams when they don't make sense to you isn't productive. Trust that if you're meant to know something, you eventually will in your own time.
