What is in the water?

One morning I was at the Sanur Beach

In general I'm a spirited man to exploring to the places that I visit in my travels. I actually enjoy being in the midst of a frenzied crowd, even while on the seashore in the morning, there is just a little guy perhaps swimming or just sunbathing.
It was a gladden morning ( among dates in April 2012) I went to Sanur Beach with the intention of seeing the sunrise. At least with no sleepy eyes but body that feels tired, for the night I wasn't sleeping (was in the Legian). I took Trans Sarbagita, the newest bus transport in Bali. Unfortunately the sun was already high as soon as I got there.

True, the it is very nice beach, yet fairly quiet. As I know, it is more frequently visited by the elderly... Who prefers a silent atmosphere, away from the noise.

However, one thing I truly thought, maybe because it's a fatigue to me, just could go off swimming. Besides, my knees were killed and couldn't have a stand for any longer. Less than three nor four elder men and women swam in the beach, me also. Yeah, I love beach, it's an immense heaven, for sure.
This often happens while swimming in the water, I am continuously haunted by the thought that there is a 'creature' within. At any times not only can attract me, but also drown me onto the bottom of the water. I'm going to disappear, probably murdered and eaten as well.

In a way, the enthusiasm of mine for the beautiful beach, but great for swimming since there weren't many visitors coming in the early morning, all just dispersed by the fear. Not long after, I was only lie-in in the mattress and ready to go home.

When I got into an attractive activity with my youngest brother, snorkeling. I always  depict for an awesome beyond any other water-activity. Everything was stunning as our first time doing that water sport, somewhere in Tanjung Benoa. An instructor taught us instantly to doing as a professional does. I and him enjoyed it, even some times we did swim beyond as beginner, indeed.

After one hour we snorkeling, we climbed up to the boat. It's starting  moving forward to the seaside, my brother and I eventually were being told the feeling after. We have no difference thing that made us almost die was the jitters of a strange 'creature' or some of wild fish would pull us in. "I was praying along the whole I snorkeling in order ain't no other devil could kill me inside the water", my brother vocalizes. Seeing not only me who frightened  about swimming in the depth of water.

If it's just an imaginary, so what's in the water?
In similar, another folly occurred. I think I was in high school. And I was on vacation along with a boy classmate in Samosir Island. It's tremendously charming and stunning sights, which in the middle of the largest lake ever in the Southeast Asia viz Lake Toba (getting there: from Medan take a public bus to Siantar--switch to another bus to Parapat--take a small ferry or speed-boat to that incredible lake ).
We stayed at a small inn, luckily near, only 10metre to let us jumping over the lake. Much more horrible, I tried to play my liberty. Go for a jolly jumping into the loch, swimming never than 3 minutes right the way. I am recoiled by that fear. I don't know why, just not very sure I could be brave to swim.

After all, I overrate what virtually in my mind. 
As of  I circulate this writing I still go for a swim.
