Can you convince yourself that you are you?

I can do it if I pull up a bad dream from childhood, lol.

When I was quite young (before age 6 because the memory is from the first house I lived in) there was some kind of TV or radio commercial that advertised an outdoor paint or varnish. There was a little jingle in the ad that went “Water on wood … uh uh no good.”

To my young mind it meant something really bad would happen which I had to see. So I went into the basement where my mom kept the ironing board in the laundry room. I got a piece of wood and I used the little bottle she sued to sprinkle water on the clothes to be ironed. I sprinkled some on and hurried back.

To my disappointment nothing happened. I’ve never told anyone this story before so I think it would convince old me.

Now of course I have told others so I guess I’m stuck going forward.

Yes. In 30 words or so. Starting with “The body is…” That’s all I’ll say here.

Yeah, I could do it. “Remember in metals class when you found a bag of weed on the floor and stuck it in your sock?”

I agree with this. The question isn’t whether there are things I could tell myself that nobody else could possibly know. That part is easy. The question is whether that would be sufficient to convince me that this message came from the future. It wouldn’t, I would think I was having some kind of mental breakdown.

But perhaps that’s fighting the hypothetical, OP wasn’t completely clear on this. Are we to assume that we already know that such messaging from the future is possible, and it’s just a question of whether we could distinguish our real selves from the impostors?

Maybe it’s time. I have three heads, but two of them are invisible.

Seriously, if there is something I have kept secret for 80 years, do you think I’m about to publish it now?

I think I could do it. I can recall many incidents, since childhood, where I was just about to voice the most stupid, innocent, but embarrassing question, and only realised just in time that it would be a stupid and embarrassing question.

Ah, if only I had realized in time.

My take on this, now, is that anyone who can remember dumb thoughts they had as little kids (and I have hundreds of them) that they thankfully kept to themselves–which I believe is “Most everyone”-- could perform this not-so-difficult feat, several times over.

No problem whatsoever.
I can describe a dream I had, or a video game idea say. Although in both cases I have written these things down (yep, I sometimes record my dreams), I can easily think of some additional details I never wrote down.

nowadays I have a hard time convincing myself that “i-am-myself” when looking into the mirror after getting up

seems it comes built in with age

:wink:

You look in a mirror? Well, there’s your problem. I avoid them. Nothing I can do about it.
