Shadow Ghost With a Triangle Coming Out the Side of It

This first started when I was in middle school (11 years old approx) and carried on throughout secondary school. To get to my school from my house was about a 20 minutes walk - I would walk with my sister part the way and she would go to her secondary school whilst I carried on to my school.

Normally I would stick to the main roads which was lined with houses both sides but if running late there was a short cut through a very tiny bit of wood - the bit you had to cut through wasn't very dense and from where you entered it you could see the exit of it.

One day I was running late so cut through this part of the wood - the exit of the wood is up a slight hill so I got to the top of it and looked behind me (no particular reason and had no sudden urge to), 'standing' at the bottom of this slope/hill was a black figure, I would say human shaped but it had a triangle coming out the side of it, like a cloak was blowing and then had frozen whilst sticking out. I could see no features and it didn't move it just 'stood' there. I quickly carried on walking and didn't mention it to anyone.

The following weeks I kept walking this way trying to see if I could see it again (I had nicknamed it 'baby' for some reason) but didn't and soon forgot about it.

In my previous post I mention about hearing noises in my house and I now attribute these to 'Baby' as there were some appearances in my room (only a couple) and when I looked outside my window.

Occasionally I would look into a corner of my room and see a black hazy figure similar to babies - these came with no warning and didn't give me a chill or anything.

Also I would look outside my window and the path that runs alongside the house (I now don't live there) had a hedge the other side and I saw baby standing almost in the hedge. Again I had no warning of this and did not feel anything from it.

I did try to investigate if anything had happened in the woods and someone told me a woman had been murdered there but I don't believe this as there are no reports of it and there was no indication 'baby' was female.

I have since heard of shadow people and consider this as a possibility but I always thought shadow people were very active and moved about a lot - hence why they are often captured on cameras set up in empty rooms.

Since I moved house I have not seen baby again and still do not know if they were real apparitions or not - I think they were as it continued well into my teens (I moved at 15)

I have done ghost vigils in buildings and believe there are beings that cannot move on and do appear to us and there is no set in stone reason why this happens

Any comments and thoughts will be welcomed.
