My "10 Years Old and New House" story reminds of some experiences I had going out to a friend's uncles farm house. I don't remember how old the house might have been but it could have been built in the 1930s-1940s, it was very nice Old Farm House very well kept inside and out.
I first started visiting there when I was 12, my friend's aunt and uncle were extremely nice easy going retired farm people. They very much lived on the main floor. What got me was the 'upstairs', I never saw or heard anything but it made me extremely uncomfortable. It was almost like walking into some type of electric field.
This was about 2 years after my "10 Years Old and New House" experience so I was somewhat sensitive to something there. My friend never felt anything but thought some of the old time pictures watched him. We camped out many times over the years but I never would have stayed the night in that house. My friend did tell me about an aunt with a very strict reputation that had passed away in one of the bedrooms upstairs. It was almost certainly something paranormal but I have no idea what it might have been. I have never, since then, felt anything stronger. After getting the $%^t scared out of me at age 10 or so, I may well have been blocking some of the things I might have otherwise noticed. By the time I was in my 20s, the effects, if they were still there didn't bother me much if at all.
ETA: I actually tested the 'feeling' I got by walking up and down the stairway to the 2nd floor. I could tell when I encountered "it" and when I left the 'area' going back down stairs. Whatever it was it didn't vary any as I walked about the second story. I have read of other sensitives mentioning these types of feelings in actual haunts, eg. (Sybil Leek working with Hans Holzer on a case in California.) In my case IDK, it could have been residual.
