So, feedback: Your story is nice and simple. It’s easy to read and the abrupt ending is quite appropriate. It is a bit like something from Monty Python.

However, beware this kind of run-on with a comma where there should be a new sentence:
“The room started spinning, and he saw planet earth from his window, he was sure he was in space.”

Also, consider using the ‘topic tags’ so your blog post shows up in topic related listings, and maybe add a ‘featured image’ so that displays in the listings too.
