I believe it is called acrophobia.
Altophobia is the fear of heights, while hypsiphobia is the fear of high places. Both phobias involve a fear of being high above ground, but altophobia may be more generalized to any heights, while hypsiphobia specifically refers to high places.
The fear of being tall is known as acrophobia. It is a specific phobia characterized by an intense fear of heights. People with acrophobia may experience extreme anxiety or panic when they are in high places or even at the thought of being high up.
Aeroacrophobia- Fear of open high places. Batophobia- Fear of heights or being close to high buildings. Catapedaphobia- Fear of jumping from high and low places.
the fear of large rooms, with high ceilings such as being inside cathedral like rooms is called meglaphobia.....
Merinthophobia
Well, I don't know what the fear of being alone at night is, but. Know that the fear of the dark is nyctophobia; maybe that helps? I'm totally nyctophobic; it's the fear of the dark because of what the mind thinks up about objects in the room which are not clearly visible. Hope that helped.
There are two phobias related to not being able to move, claustrophobia and cleithrophobia. Claustrophobia is specifically the fear of confined spaces, while cleithrophobia is the fear of being enclosed or being locked in an enclosed space.

There does not appear to be a scientific term to describe a fear of being hyper. Perhaps the fear stems from a fear of being perceived negatively, or of not being taken seriously. This is not to say that 'being hyper' is a negative trait. I've worked with many CEO's of corporations and other high paid professionals that would all be easily considered 'hyper' by their colleagues. They were all quite accomplished, both professionally and personally.
It could be caused by being hurt by someone in the past, or a fear of committing to one person and letting them see so much of yourself.
The fear of being in the dark is Lygophobia. The fear of dark or night is Nyctophobia.
