The Physiology of Dreams

This evening i was roused from my slumber with a question on my lips. What affects do dreams have on the body other than psychological? For example, if i my dream i am cold and can feel intensely the goosebumps, will those mind-based sensations translate into physical manifestations? If someone were to observe my body, would they see the flesh raise? The action of the erector pili?

In waking life, if a person is frightened (a psychological experience), there are noticeable physical reactions to that fright. Pupil dilation. Increased heart rate. Muscle tension. Possible sweating. If a person were to be severely frightened in dream life, would an observer note changes to their body similar to those experienced during wake states?

I'm sure there has to be studies on the subject. I've had a bad dream and woken up in a sweat before, so I can imagine other physical reactions as well.

i don't know about dreams but i know about rats. seriously, like a rat is actually going to attack me. it just wants the garbage. but here is the scenario. walking past the sub to pick up my bike. rat runs out of a bush to pick up a piece of garbage. taryn freaks out. pupil dilation. increased heart rate. muscle tension. an audible "fuck no." and then a 180 degree return, forging a new path where no rats go.

irrelevant maybe, but i'm still freaked out about it.

what if you are having a nightmare about being murdered and you don't wake up?

I remember I once had a dream that Stormtroopers had invaded by house and I was cornered and they shot in the arm and it hurt so bad! But, I was just sleeping on my arm.

I think the content of our dreams are a manifestation of the waking world physically. For example if you are cold, you will dream you are cold. But if you are terrified your body will reflect that in sweating and increased breathing.

These observations are not based on science, but rather my own feelings on the matter.

Oh and when your body does that crazy jerking thing when your falling asleep it's because your brain thinks you're dying and sends the stimulus to your muscles. Go brain!

I wonder what I was dreaming when I punched myself in the face on saturday morning. I know what the physiological reaction was, but the reasoning has escaped me
