Google Analytics question

Does am wrong or something is not properly adjusted? Today i checked the analytics after some time on a website that i do not force too much with posts and i saw a big organic traffic change. I usually get about 20-30 sessions on that site but today i got 168 sessions. So i said i must check what keyword/query the traffic was coming from, i go to the ACQUISITION > Search Console > Queries and i found just 8 clicks are made from the top "Search Query". Is this something you familiar with and is there something i can do to show me real and true results?
