- Fear of the dark
If you have fear of the dark you could have this phobia called Nyctophobia. According to Wikipedia it is a phobia characterized by a severe fear of the dark. It is triggered by the brain’s disfigured perception of what would, or could happen when in a dark environment. It can also be temporarily triggered if the mind is unsteady or scared about recent events or ideas, or a partaking in content the brain considers a threat (examples could include indulging in horror content, witnessing vulgar actions, or having linked dark environments to prior events or ideas that disturb the mind). Normally, since humans are not nocturnal by nature, humans are usually a bit more cautious or alert at night than in the day, since the dark is a vastly different environment.
- Fear of Blood
Are you fear in blood? This is a phobia called homophobia, Wikipedia said that blood phobia is often caused by direct or vicarious trauma in childhood or adolescence. Though some have suggested a possible genetic link, a study of twins suggests that social learning and traumatic events, rather than genetics, is of greater significance. Accordingly, painful experiences can condition fear to blood-injury stimuli. Investigators typically classify around 60% of self-reported onsets of blood-injury phobia as beginning with conditioning experiences.

Some people scream, cry, have emotional outbursts, experience trouble breathing, sweat have heart palpitations, or even faint when they come in contact with an area near spiders or their webs. In some extreme cases, even a picture or a realistic drawing of a spider can trigger intense fear.
