If you're on PC click the cog under your name on the right to open the menu then select "yes" for "Auto media preview".
If you're on mobile click the three lines in the top left corner, then click the cog and select "yes" for "Auto media preview".
I just noticed while writing this that this setting doesn't seem to carry over between PC and mobile, so if you switch between both you'll have to change the setting on both platforms.
If you just want something super relaxing give Stardew Valley a try. It's cute but all the characters have some real depth to them.
