Why does time squish together for me?

I am kind of alright estimating how long a task will take, but usually I get it wrong by a fair bit. The weird thing is, when I remember stuff, it’s all squished together, like it all happened really quickly. For example, I had had my laptop for a year, but when someone asked me I said a few months, and it really felt like that. I can’t guess how long ago something happened, its all squished together and I have no sense of time frames, its like it just happened. You could say its all wibbily wobboly timey wimey.

Why does this happen? I’ve yet to meet someone else with this sort of thing.
