Impressions decreasing in search console but number of clicks are increasing

Hi,

I'm new to SEO and manage a 4 month old blog. I'm observing a strange occurrence in my search console data since last week - the number of impressions have halved, but the number of clicks are constant in search console.

I've checked sections like manual actions and security issues in the search console, didn't find any issues.

Is there anything that I need to worry about? Or anyone can please explain why is it happening?
