It relates
that there was experience, but not
what that experience was - We can read and understand that they're reporting their own experience, but that's about it.
One could say "In my experience, the earth is flat", but there's not much a conversation to be had there.
One could say, "In my experience, the earth is flat - I got in my car, went for a drive in one direction, and eventually hit a cliff at the ocean instead of finding myself back where I started". Now there's something to talk about.
(To be clear: this is the internet, and a limited communication medium: I'd assume OP could relate details about their experience, and it's totally reasonable that instead of taking the time to do that, they went outside and touched grass)
