Are we living among synths?

Recently I've seen a previous post about fake people, so I wanted to share what's been happening to me.

I've been noticing several fake people while I go out in the city. When I'm sober, I don't notice anything strange. However, when I go out high after using weed, I see the same people that I saw hours earlier in completely different places. I feel like they know I can see them and that I know something strange is happening. It reminds me of the synths from Fallout 4, who believe they're human until a DNA test proves otherwise. I think this experience could be caused by either a glitch in reality or the effects of weed.

One possible explanation is that it's a glitch in reality and you can see them only when your perception is altered. The same people appear in completely different places only a few hours later. Sometimes I also feel that they know I can see them and that something unusual is happening. Because this happens so often, it makes me wonder if reality isn't working normally.

Another possible explanation is that it's caused by weed. I've thought that these experiences could be paranoia or another effect of being high. The strange part is that they happen almost every time I use weed, while I never notice them when I'm sober.

In conclusion, I'm not sure which explanation is correct. I think these experiences could be a glitch in reality or simply an effect of weed. What do you think?
