I have 2. The first one happened when I was 19. The room I grew up in at my parents' house was in this back hallway and everyone always thought it was creepy. it felt like someone was always watching you. Also an old woman died in that room many years before we moved in. I was back home after my first year of college because I was in the dorms that year. I woke up in the middle of the night to a woman in a white robe or gown standing at the foot of my bed looking at me. She was giving off a white light and I felt a strong sense of benevolence and protection coming from her. She was smiling very warmly. I felt like I was a little bit under a spell, I was aware this was odd but I felt so peaceful and calm in her presence. After a minute or so, she turned and walked out of the room and into the hallway... I watched the light fade down the hallway. When she was gone, the spell was broken and I was like what the fuck! If I was asleep during the encounter, then I really fooled myself because it's not like there's a break between seeing her and definitely being awake, it was continuous.
Anyway the next morning I asked my mom if she had a white robe, at breakfast. She was like uh, no, why do you ask? I asked her if she came to check on me last night, and she said no. Then I told her the story and she got really clammed up about it and changed the subject. Then like an hour later she came up to me, totally unprompted, and was like "actually I forgot, yes I came to check on you and yes I have a white robe, that was just me". It seems obvious to me that she was just scared, and my mom is really good at convincing herself of things she wants to be true.
The second experience was by far the most unexplainable though. My ex and I agreed to cat-sit for someone at her school, to come over once a day for 2 days and feed the cat. Everyone was out of town so they gave us the key. They also made a point to tell us that their house was haunted, and if that was okay. I was really intrigued and said it was.
The first day we went over there and as soon as we walked inside, it seemed like the house had a family in it or something. There were clear as day footsteps upstairs, I heard 2 door-closing noises up there too. And down the hall from the entry room I completely distinctly heard the sounds of a family eating a meal, with the clinking forks, plate sounds, the faucet turning on sound, and low murmurs like I could almost make out what they were saying but not quite. So I thought, okay someone must be home. I started walking down the hall to say hi so I wasn't just a stranger unlocking their door and coming in. As soon as I got to just before I could see around the corner into the room, the noises stopped and it was utterly silent. The kitchen was definitely completely empty and still. It creeped me out but also fascinated me and it didn't feel ominous or anything. I experimented a little and walked back a little bit down the hall and the sounds came back, everything about my perceptions told me there was a family eating breakfast in there. Went back to the spot, and it cut out again. It did this all the time.
After that, we went upstairs to feed the cat. I was kinda nervous because someone clearly seemed to be walking around up there and quite active. But like the kitchen, as soon as we got near the top of the stairs it was totally quiet. Instead I started to hear people walking around downstairs where I had been. The room the cat was in was the only part that was creepy, that room had a really sickening feeling, I wanted to get out of there and I think the cat did too, but we were under strict orders to not let the cat out of the room. I felt bad for that cat.
The next day we came back and it was exactly the same. It was like there was a recording playing except for some reason you couldn't directly observe it, and I really don't know how to explain it, I have not come up with a plausible reason why I would have experienced that besides paranormal reasons.
