One point: having such dreams does not mean that you secretly have such desires in waking life, so no need to worry about sexual attraction to animals or incest, unless you ha e had such desires in waking life having them in dreams does not mean that you actually desire such sex.

Wolves have often been used in fictional stories and fairy tales. There is a lot of symbolism in our culture about wolves and ware wolves, and quite a bit of sexual connotations which do not mean that we as a culture actually are attracted to wolves, but rather wolves are used symbolically. A man with a bad boy reputation may be called a big bad wolf, and if he pretends to be innocent to attract an innocent we say that he is like a wolf in sheep's clothing. On the other hand actual wolves are known for mating for life and having strong pack loyalty, and that is also known in our culture, so you could have dreamed this dream because you were hoping to have sex with someone with strong family values.

The dreams about making out with childhood friend and with cousin may have been meant to shock you. Sometimes I think our subconscious likes sticking it to the conscious. Showing it something meant to provoke a strong negative response. These dreams could have been due to strong taboos: having sex with childhood friend and family member are taboo to you, so your subconscious shows them to you in nightmares basically. I believe that one can have nightmares that are not scary while they happen but only become nightmares once we wake up and remember the dream and feel shocked by it. Those kinds of nightmares are my least favorite because then I also tend to feel guilty over not realizing in the dream that this is inappropriate. The thing to remember is that while you are in a non-lucid dream, the sense of right and wrong is often not aware enough, and we shouldn't feel guilty or blame ourselves because not only are we not in control but logic and morals are not getting applied - out brain is adding 2+2=swan and not realizing that there is anything wrong with flying hippos or killing people.

Sometimes such dreams also may have some symbolic message from subconscious or you can look at them and find a useful insight even if the meaning was not originally there (or maybe was, who knows).

However, some dreams are maybe better forgotten or ignored, and some of yours might fall into that category for you.
