Adrenaline or Fear ever boost your experiences?

[Battlr]

FOAF has had a few experiences he would like to share, and he would also like to know if anyone has every had the adrenaline from fear boost or intensify a trip in a positive way.

The first story didn't even involve tripping.
It was from a cigarette. At the time, he was living with his parents and didn't want to be caught or seen smoking. He was out on the stairs leading up to his apartment. At the time, he was not a smoker and still got and enjoyed the lightheaded feeling from tobacco. He took a big drag, and as it started to hit him, a car on the street that was driving by his house honked his horn fiercely.
Panicked, he looked around, and when he realized that it was just some passerby. But his heart rate was skyrocketing and he felt a very nice body high from the adrenaline and fear. In the end, it was a very enjoyable experience.

The second one had to do with mdma. Long story short, my foaf had to run from the authorities and ended up at his buddies house.
He had taken mdma that had 2C-B in it.
Before the run, he was only experiencing a good mdma roll. Afterwords, as he laid down on his friends bed (Still scared shitless) he started seeing pretty colors and designs on the ceiling. Upon looking in the mirror, everything was morphing and changing.

He is convinced that in both scenarios, the adrenialine that was released from the fear heightened the experiences.

Has anyone ever had similar things happen?

He would really like to know ^.^

Yep. Fear is a major ramp up to the intensity of any experience.

I like to skydive and bungee jump and crawl around in caves because I find fear to be a huge rush that is fun to play with.

Caves because I'm kind of claustrophobic and they scare the beejeebers out of me at times.
