From a teen in France: I sometimes see things that aren’t there. It doesn’t happen often, but I do. I sometimes see shadows that aren’t there from the corner of my eyes ( I know that they aren’t there because when I turn to look at them they’re gone ), but apparently it happens to a lot of people so although it’s kind of scary it doesn’t worry me.
I used to see my cat, too, from the corner of my eyes, while he was still at my grandparents’, but I guess it may have been due to light and shadows ( of furniture ) and to me thinking about him and missing him, so it doesn’t really worry me either.
What worries me, though, are spiders. I saw one twice, so that’s not much but the thing is, unlike with the shadows, I really thought they were real. They both had a red head, a red body and golden legs. Both times it was late at night ( or early in the morning, it’s up to you ) and I hadn’t gotten much sleep in a few days but I wasn’t that tired.
One time the spider was next to me on a wall that was, like, 30 mm from my bed, and I saw it when I woke up during the night and went to sleep in another bedroom ( after having told my mum about it and having found nothing upon returning to my room with her ). The other time, which was yesterday, I saw it BEFORE I went to sleep ( I might’ve closed my eyes for, like, 10 min with the light off then switched the light back on but I didn’t fall asleep ) and my cat was right next to it but didn’t see it, and at first it was on a wall then it went on the floor and on another wall in front of the first one then back on the floor, and it was scaring me to death so I killed it with a shoe, and proceeded to avoid the shoe the following day only to discover that there was no spider under the shoe. I know that it’s not much but I’m still worried, why do you think I see these things ( especially the spiders ) that aren’t there ?
