Just wanted to share my story with the Breather Spirit. First, I heard this when I was around 16, in the apartment I lived with my parents (in Latvia, Riga). I woke up around 4AM and heard the sound of breathing from the far corner. It sounded tranquil and rhythmical, like somebody is asleep. It really terrified me, I just pulled the cover over my head listened to the sound. It lasted for more than an hour, I believe. It ended with the morning sun, when my cat run into the room and started to mess around.
This apartment had always had weird, eerie feel, but nothing too spectacular. My parents claimed they have seen shadow people on several occasions, they also had a vivid sleep paralysis experiences. Once my Mum comes into my room asking what did I want, why I was calling her - but I never called her! But I just always thought she just has some kind of psychic ability. I only have heard knocks on the window at night (we live at 5th level). But I had always wrote it off to imagination afterwards. But this time, with the breathing sound it was different.
After some time I heard the breathing sound again - at night.
Then I eventually moved out from the apartment, as I started college and after few years I heard the sound in another apartment altogether - It surprised me, I must say!
The strangest experience occurred much later (after 6 years or so). I had moved to another country, and stayed in my friends flat in Dublin. It was quite difficult time for me, I lost my rented place and my job too - so it really sucked to be me back then:)... Then, during day (!), I heard the Breathing Sound in flats living room. I freaked! I wasn't so afraid, as I tend not to be so terrified during day... So I could even point where exactly the sound is coming from - it was from the middle of the room, very low - could be like a lying down dog! There was nothing there. THEN I freaked and ran to the other room to tell my friend. When she came in, it was gone. Friend told me that It can not possibly happen in HER flat (even she is a strong believer in paranormal) - that she has been there for years, and the flat has a nice atmosphere. She told me that I must be hearing imagined things due to stressful events in my life and I needed to chill. Weirdly enough, quite soon after hearing this, my life improved - I got another job and a great apartment to rent.
After I moved out, my friend rang me to tell that she has no choice but to believe me - that she had heard the breathing in her flat herself! It occurred there with her only once - It is almost like the spirit wanted to prove his existence, it didn't want to be diminished. She also said that this didn't scare her at all, that she could even sense some positive vibe from its presence!
Then, after several years - a week ago from now actually - I was visiting my Mum in my old childhood apartment. I woke up around 5AM, I think I actually woke up from the breathing sound. It was coming from the same corner as when I first heard it back then. This time I surprised myself: I was curious, not really terrified. I was trying to tell myself before that during night-time our mind / perception can work tricks on us etc. But this time the sound was unmistakable and clear: It was peaceful, like somebody is deeply asleep; very quiet inhaling, loud exhaling. I was listening for a while and even sat up on my bed. It almost got louder as I did it! I think It wants to be heard! I stand up, It was still there. It sounded more like a human this time. So I stand in my room thinking all possible rational explanations: I even considered I'm just hearing my Mum in the next room, but it is not really possible. The radiators are turned off for the spring season, we live on 5th level. It was quite light in my room, I could clearly see everything. I turned on the small light on my night stand. The moment I did so, It stopped - now I almost regret doing it... Only later on I gathered that I should have had recorded on my phone - yes, I think the sound was in fact that loud.
Anyway, I believe we are always watched - we might have several spirit guides; I tend to believe it came to comfort me previous time... May be it is some spirit form that has no other means to communicate as only to breathe... May be I had a pet in previous life who came over and wants to be around?... May be It is choosing to only breathe, not to completely freak me out... I would love to read your experiences or ideas about this entity...
