Fear as Feeling - Fear could however be simply manifested as a subjective feeling, a sense of uneasiness or unconscious perception of some sort of danger or threat that may not evoke strong bodily reactions. Fear as feeling is thus unconsciously released in dreams, slips of tongue, lapses of attention etc.
Fearin Anxiety - Fear as a feeling could also be the subjective basis of anxiety as when internalized and even unexplained anxiety has a general feeling of fear. Anxiety thus also begins with a fear but this could be largely unconscious, internalized and more generalized. But anxiety has distinct bodily reactions and that is how anxiety differs from fear as a feeling.
Fear in Phobias - Fearin phobias consist of persistent pathological emotional response towards specific objects or events. The difference between anxiety and phobia is that phobias are always externalized whereas anxiety is internalized and fear again being externalized as an emotion or internalized as a feeling would be a part of both anxiety and phobias. However phobias are not emotions but pathological responses consisting of fear as a complex emotion and bodily reaction. Since phobias are compositions of emotions and strong reactions, the reactions are expressed in exaggerated forms in phobias so individuals with phobias would react in extreme ways and could develop a state of panic especially due to the extreme and uncontrollable bodily reactions.
In therapeutic treatment of psychology it will be necessary to understand the origin of fear and this could be done with neurological studies and studies of bodily reactions and mental states. Fear as simple feelings or complex emotional responses should be identified in specific situations and extensive fear could be studied in anxiety and phobia.
