Is it normal to have an indentation in my skull above the temple?

The temple itself is an indent, but above that indent is not likely to be another indent. As the others mentioned go see a doctor and have them touch your head instead of expensive scans. If you are feeling it, they should too. A nurse should also be able to feel it and tell you if something is concerning should your local doctors office be busy.

There are some interesting things that I should mention. Just as an off hand coincidence - it doesn't have anything to do with anything else - just a series of coincidences that I noticed that may have something to do with it.

There is a picture in the Chinese district of town that has a picture of the statue of liberty but with four eyes (similar in many respects to the picture of the four eyed image in Carl Jungs man and his symbols - and the shelter that is closest to the jung institute happens to be in the mission district). There is also a picture of the statue of liberty on fifth street that has a ball and chain on a homeless shelter. In the chinese district of town there is also a picture of the buddha with head phones on (a reference to princess leia?). And whenever I'm sufficiently annoying people are going around and holding hands.

No one else in the city has a divit in their skull but there are any number of people that are wearing ear phones (because they have to?).

So the question is is someone that is terminally ill irradiating their hands and then pushing them against my skull in the homeless shelter at 1050 South Van Ness. Weird. I should also mention that both the shower and the coffee machine appears to be making me sick and I believe there is something interesting about the water supply so that the fumes will fuck up my chest. They have this weird/bizarre belief that "kings" are "dead" - because if you're going to kill someone or sicken them the easiest way to do this is if you're already terminally ill yourself so you can do stupid shit like this.

It's not that I'm not fucking terrified more or less all the time I just can't keep a secret for shit. So I end up asking everyone about it until it either stops or someone reassures me it's not true.

If I understand you correctly, that's normal. But this really isn't the place to ask. Maybe try posting a photo reddit if you don't want to see a doc?

Maybe you should ask a medical professional about this.

Ask a doctor, nobody can make a meaningful diagnosis from such a brief description.
