The option in the panel menu is for how the pages are displayed inthe pages panel. Vertical means a single column, horizontal means there will be rows of spreads as wide as will fit the width of the panel.
It sounds to me like you want to view a two page spread with the binding along a horizontal plane, like a calendar. To do that, slect the spread(s) in the Pages panel, then from the panel menu choose Page Attributes > Rotate Spread > 90 degrees CW (for layouts that read left to right, CW for right to left layouts).
I received a PM from tonquin asking for more details, so I'm going to post it here. This is a screen capture from CS6, but it should be similar in CC:
You may find working this way is disconcerting, though. The ruler zero point "appears" to move (it doesn't, it rotates with the view), and if you undo the rotation your height and width values will be swapped.
What I'm doing: I want to create the Front Matter to a book.
Steps I've taken:
1. New Doc - Default setting - change margins - save as preset, click OK.
2. On Pages tab drag None options onto my page - click on dropdown menu and Insert Pages (I chose 8) - No Master, Insert After page 1
Problem: The pages show as one big horizontal spread; I need them to show in vertical 2-p spreads like they will appear in the book
1. Pages window - View Pages - make sure "vertically" is checked; Panel Options - Masters - make sure "Show Vertically" is checked.
2. Uninstall InDesign. Reinstall InDesign. Result: This did not fix the problem, although I don't see why it shouldn't have.
OK. There's definitely a problem. In the screen shot I don't see brackets around the page numbers, but let's verify that page shuffling is enabled. Click on the leftmost pae in the pane, then hold the shif key and click on the rightmost page, so they are all selected, then right-click on them and make sure that BOTH Allow Selected Spread to Shuffle and Allow Document Pages to Shuffle are showing checkmarks.
If shuffling is alread enabled (checkmarks show), then yes, you do need to trash the preferences. Here's the link again: Replace Your Preferences
If you haven't done a lot of customizing, the keyboard method is OK, (you're going to lose customizations with either method, but you don't get to restore the old ones if it doesn't work when you use the keyboard).

I'm a new user of InDesign and this is my first attempt at a project. I feel like I've been sold a defective product. Why should I have to do all these fixes on something that is a brand new purchase? When I Uninstalled InDesign and then reinstalled it, why didn't that action give me a product that was usable?
I don't know why you developed problems. What you are seeing is not normal -- I've never seen a similar report where ID made single spreads like this. But I am trying to help you resolve the issue.
If the problem is damaged preferences, they are not replaced automatically by uninstalling and reinstalling. You must elect that during the uninstall process, or do it yourself using the proceedures outlined in the link. If it is not the preferences, and you didn't manage to turn off page shuffling yourself in some way you don't realize, then there is a problem in the installation, and it most likely failed due to a conflict with something else running on the system during installation.
But the most important first step is to check whether page shuffling is enabled, and if it not to re-enable it.
