Don't fear a fear.

Many of us have fear of heights and it is common. If I am standing on the top of very tall building and I look below, like you I would also feel scared for a while. I also had fear of dark long back and later on it vanished when I realized that there was no ghost in the dark. . I also fear seeing a snake. Though I know that it won't make any harm, until and unless you disturb it.

@dpk262006 I had it only until 3,4 the grade . I dare not to go in dark rooms at that time. It's good you overcame your fears too

@CuriousGab It means that you used to fear when you were around 8-9 years old and subsequently the fear vanished.

Bats are generally found in dark and moist, damped and unused closed rooms etc. Normally, we do not see bats in our house. I am wondering what makes you fee afraid of bats? You see it is a common fear that one day we would lose our loved ones. Everyone has this fear and it is understandable.

@Rashnag I had no idea that you have a huge tree near your house and bats in fact visit your home. It seems scare to me.

@dpk262006 We have big trees here so the bats come here and at night lose direction thereby entering our home from balcony

It is weird that you feel you could get buried alive. It could happen in rare instances such as collapse of a building due to earthquake etc., which generally won't happen in your area. I meant earth quakes may not be of severe intensity in your area. Some people suffer from claustrophobia and I think it is not uncommon. I also feel suffocated in crowded spaces. I remember once we went to see a very famous monument - Taj Mahal. On that particular day there was so much crowd that one cannot imagine. There are graves of the King and his queen in the basement of Taj Mahal. We went there and crowd was more than its capacity. Our guide was explaining the background to us, however, I felt uneasy and I told him that I feel suffocated here, we would go outside and then you could explain it to us.

@LadyDuck Yes, you are right that anything is possible in this world. I understand that structure and shape of catacombs was such that you would have felt suffocated in that and you just came out.

@dpk262006 As you have seen in Miami, a building can collapse even without a earthquake, it could be a structural problem or a terrorist attack. I know what you mean, during a tour in Rome we were visiting the catacombs, but I could not stay down there, I had to go out.

Worrying about future is not fall into category of a fear. We all think, worry and plan about future and it is a natural thing. Worrying about our health is different than fear.

What made you feel nervous? Was it a untoward happening or something else?

@dpk262006 As I said I don't remember when was the last time I felt like that
