Being naked in public is the least scary nightmare I've heard of

I hate when i get nightmares, and it feels real. Like sometimes itll feel like fast thumping on my chest.

I hate nightmares where you know you're having a bad dream but can do nothing to stop it. Like being unable to move or scream.

I hate those slowmotion-falling dreams, and those dreams were i am unable to punch or run :(

Anyone else here after waking up from a nightmare ?

I used to have a lot of insane nightmares as a kid and the reason was because I was suffering from hypoglycemia (due to undiagnosed Type 1 diabetes). The nightmares was a defense mechanism for by body to wake up because essentially I was dying and needed to raise my glucose levels. Just thought I'd share in case it helps anyone.

This guy: “I have nightmares about being naked in public”
Me: “I have nightmares I’m in a horror movie”

When we close our eyes, why do we see strange patterns, shapes, aside from say, closing your eyes after staring at a bright light?

My nightmares usually consist of me wandering around in a haunted house, which sounds ridiculous and only kids should be scared of that stuff, but they feel very real and terrifying and usually I’ll have a family member with me that either gets separated or attacks me for some reason

[karenmurphy]

When I dream, I am always aware that i am dreaming, but in morning, I can remember the feelings like fear, happiness, Euphoria but content is always missing. I often sit on my bed trying to figure out what i dreamed coz i want to know why i feel so Euphoric.

HOW HAVE WE NEVER TALKED ABOUT THIS BEFORE?!

[rajjgaming]

I wish i has dreams of being a super hero or something, wish i could lucid dream for the entire time I'm a sleep and just have fun

Nice movie. However, it is worth reaching for oils from Weedborn.

Thanks for putting a little humor into this. I have been waking up every single hour just to fall asleep and have another nightmare and wake up the next hour and repeat it until daylight. Obviously I don't want that to happen so I'm just pulling an all nighter now lol

[changedlies]

what does it mean when you have a nightmare about running really slow and you can't get away?

[jazmineo]

I used to, and still sometimes do suffer with frequent nightmares. I found that sleeping without the TV radio or anything on helped a lot. It'd be interesting to find out if external stimuli really does play a role in dreams/nightmares. We always see this used in TV and movies.

How do scars form? And why do they have a different texture and look?

I once had a nightmare that a basketball-shaped bird flew into my face, and the previous day a basketball hit me in my face. This was in high school. Also, I am afraid of birds. My fear and the previous day's activity combined into one and terrified me in my dream.
