Halloween comes with costumes, candy and horror flicks — but scary movies aren't for everyone.

• Why it matters: Whether a scary movie makes you feel good or bad depends largely on your early experiences and the context of feeling that intensity, Axios' Carly Mallenbaum writes.

What's happening: A perceived threat — like a horror movie jump scare — can activate the body's automatic fight-or-flight response.

• That means the sympathetic nervous system ramps up, leading to increased endorphins and "all of these different neurochemicals that … are trying to help us survive," says sociologist and author Margee Kerr.
• "While that's the general experience of most humans, it does vary between people and even within the same person — and a lot of that variation can be explained by personal experience and history," Kerr tells Axios.

Zoom in: The physical sensation of your pulse racing and your body's stress response taking over can range from feeling awesome or awful, depending on your perspective.

• If as a child you dressed up with friends, ate candy and went to Halloween events, "you've got lots of these different environmental context cues that tell you that in this situation, [the fear response] feels good," Kerr says.
• But if you had a similar physiological response in the past to a truly life-threatening situation, you might want to avoid being scared at all costs, she says.

One tip if you do feel uncomfortable: holding someone's hand.

• Research suggests that when loved ones hold hands, loud sounds and stressful situations don't seem as bad.
• "You even get a benefit when it's a stranger … just skin-to-skin contact is so powerful," Kerr says.

Here's a song to start your week from reader Jeff M., from Madison, Wis.:

• "The song 'marjorie' by Taylor Swift is such a heartbreaking yet joyful tribute to her grandmother, who herself was an opera singer."
• "When you listen closely, in parts of the song her grandmother's actual operatic voice can be heard. It gives me chills every time I listen."
