This weekend when you had first class meeting I was in "Mrówki" - medievial watchtower. It was rebuild around 20 years ago and now there is heritage park. It's located in the middle of the forest near lake and marshland. I was there from Friday sunset to Sunday sunset.
When we was arriving (me and my friends from historical reconstruction group) we saw UFO. It looked like camp-fires flying in air. First we saw few of them on cloud above forest far away. It was funny, but when we drive in this forest we saw about twenty of them. They started to flow in circle above us. Then it started to be scary. In the end when we was leaving forest we saw one of them starting from field. We stooped and looked from very close.
I thought it may be hot air balloon, but this fire was too big and although we was very close we can't see anything except this fires. Also it was strange for balloons to flying when it's so dark. By next days we were asking people living around if there was some balloon event that day, but they knew nothing.
So that fires will stay mystery for us.

But UFO was only beginning of strange events on this place.

Last year when I was in Mrówki I felt very clear energy of that place and this year I knew it's some way dangerous place. Plus I was really scared by that UFO so this evening I drank some bear to close my energy sensing.
Next afternoon I was lying on pier above lake and enjoy warm sunlight when I decided to draw some energy. But energy in that place is relay strong and instead of flowing gently it hit me with its warm and power. Then I decided to don't drink that night and rebuild my ability to work with energy. For sake of this place.
Most of ground inside palisade around watchtower is like energy-dessert. I couldn't sense there energy of earth (usually I don't have problems with this). Pier is one of very few exceptions, I think it's because of being above water not ground. I really wanted to help this place, which is one of most beautiful places I ever seen. So I took energy from sky and bring it to ground. I was only transmitter in this process. I felt white energy flowing through whole area farther and farther. I repeat it 3 times in this night and once at morning when I was walking around whole object.

But energy couldn't reach hill with watchtower. So I went there to bring energy special for that place.
I started from 2nd floor but while going there some man-ghost on 1st floor was looking at me. He knew that I see him and he was waiting. On 2nd floor I called white energy without problem, but when I started to fell tower to find dark places I heard low sound in background, it was everywhere and wasn't sounding nice. I cleaned 2nd floor fast but 1st wasn't so easy. After long time of work with energy in many of ways, I think it was around hour, I finished but even if I was working with energy of sky, not mine I was tired so I must stop.
We were leaving very soon and I couldn't do anything with ground floor and ghost. I'm also sure there is a lot of different ghosts. Others people often see them and fell them in very negative way. In that weekend I saw first time some of my friends scared or nervous. Watchtower in Mrówki is strange place. People living around said that in late autumn sensitive person can't make even one step behind gate of heritage park because of dark energy.

While cleaning tower I also cleaned myself. It wasn't my intention but it just happened. I slept like after bioenergotherapy (I have no idea how it's in English I hope you know more or less what I think XD) and when I woke up I felt somehow different. It's hard to explain...

You say this tower has been there since medievial times? Wow, no wonder it is imbued with so much conflicting energy. The tower has witnessed a lot of lifetimes, there is much imprinted there. You should make sure your own energy is shielded before you return, that way you won't be so overwhelmed with everything hitting you all at once.

Yes, I've cleaned my energy few times since I leave that village.

Watchtower is there since year 1000 or something. It was ruined around 1500 and after 1970 there was some archaeological research after which tower was rebuild for rich man connected with politics. Local people are saying that in basement of this tower there have been made some human research.

Brrr this tower may appear scary but somehow I just love it
