I do not think i have any phobia. But, sometimes I think It Is because I have no been in front of a specific phobia situation. For instance, I have not been close to a big spider or inside a very small room. So, maybe you could have a phobia but not to be aware of It.
Althougt I have been in some situation in which I have been very scared, I do not have a psychology diagnosis of clinical phobia, I mean, my fear is normal and controlable. For example, some years ago i went to a cave with little spaces and water in the floor, I feld scary but I get in calm some minutes after.
I consider you have a phobia when your emotions and arousal are out of control, for this reason I beleviebe I have not phobias.
