This happened during a visit to Santiago de Chile, some twenty years ago.
I stayed at a hotel in a part of town called Barrio Brasil. My room was not fancy nor bad. Just a cheap stay for a couple of days. I got the keys, left my bag and headed out on town.
I got back in the evening and went to bed. Right there and then the atmosphere in the room started to change. A unpleasant feeling started to grow. After a while the feeling was so intense I put the lamp back on.
The feeling is difficult for me to describe. Strong general discomfort mixed with anger (someone else's anger) are the best words for it. Have you ever felt a bad feeling in a room after a feud between angry people? This feeling was similar. Only it was worse, much much heavier. There and then I thought it was all in my mind and tried to sleep but it was impossible. The feeling lasted.
At one point I got a vision of a person yelling. I don't know if the bad feeling created the vision or if it was the other way around. Nor can I give a good description of the "being", except for black hair and something like a negative glow of anger surrounding him or her. The vision ended quickly but the discomfort was still there, the lamp stayed on for the rest of the night.
I was still scared and very tired the next morning but too insecure to ask for another room. I was 21 years old and did not know how to handle the situation. I absolutely did not want to disclose the reason for changing to another room. The next night was as bad as the first if not worse. I've never experienced anything remotely similar to this day. I'm older now and certain that it wasn't my imagination.
The bad feeling lasted only as long as I stayed in that room. So what was it? A psychic I spoke to briefly said it could have been a memory of something negative that had been taken place there at one time. Santiago as many cities in Latin America has a history of war and suffering so what the psychic said sound possible. If someone has any thoughts, please share.
