Out in the woods, I didn't have any weird experiences, except for one time, but these were caused by sleepdeprivation (army exercise, staying awake for 72 hours and that DOES play tricks on you!).
But I allways feel I am not alone when I walk through the woods and I do believe in forrestentities/spirits.... Correction, for me they are a given fact, not a belief. My wife even told me that my behaviour and level of allertness changes, depending on the terrain I am in. In deciduous forrest I am quite relaxed, yet alert, but when I enter pineforrest my levels of allertness rise conciderably!! Open ground seems to make me uncomfortable. I was never aware of this, so I think this happens instinctively. Why? I don't know.... previous live experiences??
Personally I am a firm believer in those things we can not see/feel/understand and I know I am visited on a regular bases by energies/entities not from this world.
I had this confirmed by my oldest daughter, who has this too. One night she woke up, crying frantically. When we calmed here down, we asked her what was wrong and she replied that that man in the bedroom doorway, should leave. I had felt a presence, but did not mention it to her. When I asked here how he looked like she described my grandfather in detail, but she has never seen the man, nor has she ever seen any pictures of him!! The man had a heart of gold, but a stern face and an impressive posture.
And I have had quite some experiences through my life, similar to that. For me the "other world" is a fact, no matter how ridiculed I am for that.
Do I make sence? Don't know, don't care. This is my truth
