What Are The Little Brown Bugs With No Wings And Are Shaped Sort Of Like A Tiny Grain Of Rice

What are these little, red, six-legged bugs?

I have found these bugs a few times on a few different places around my house. They seem to like to cluster.
I have also seen this long brown "thing" very near by all 3 times (also in the album below). It has multiple sections, and has a spike looking thing on it. Actually it looks more like a single piece of sugar grain on each section.

Can any one identify these things?
They look like ants, but not quite. I've never seen these before (At least, I don't think I have).

Don't ask what anything feels like, I'm not touching anything until I know more about them. Haha
I will try to answer any additional questions about them if anyone needs more info.

If possible, please link to an article (not Wikipedia) about them.

What are the little brown bugs with no wings and are shaped sort of like a tiny grain of rice?

I found these little bugs in my bed. They usually show up when I have the window open, but this time they didnt. They just came on their own. I tried looking them up to see what they were, but I couldn't really any of them. What could they be? Are they fleas, bed bugs...? All answers are greatly appreciated!

Dead bugs in my kitchen and bathroom!!!?

I live in a modified trailer as part of my university's on campus housing, and when I returned from our three week winter break, I found hundred of these dead bugs, they had all congregated in the bathtub and around the toilet seat, and under the blinds on our glass sliding door. They are very tiny, and have two small wings, that are folded over their backs, instead of extended outwards. There was no food out, and no one had been in the house, and I cannot find something that they were trying to find, besides water. There are a few living bugs, and I want to know how to get rid of them, and to prevent it from happening again!!
