The Power Of The Mind example:
2 researchers were walking through the jungle, they were near the equator where they set up came for the night. It was scorching hot that day and night that one of the researchers woke up in a cold sweat and couldn't get back to sleep. All he wanted to do was get some air and cool his body down so he could go back to sleep. He heard a zipper and instantly felt cool air coming into the tent and was able to fall back asleep.
The next morning he turns to the other researcher and says, thanks for opening the tent last night so I could sleep better. The researcher replies, I didn't open the tent, zipped down my sleeping bag.
The power of the mind, maybe that is what you were expierencing.
There is a situation that i've expierenced with this, my psychairist told me about this, and I've posted it. Maybe I will share mine in time. It's weird.
