A bright, white star like light, rising quickly.

It just rose up quite fast with no sound then was obscured by the roof of the building.

I had woken up in the night because my boyfriend was having a nightmare and was shouting in his sleep. I sat up in bed and began watching a cruise ship out of the window.I saw a small, faint flash in the sky above the cruise ship before seeing the UFO. Also,last Saturday, 18th April, I was sat on the balcony around 08:30pm. There was lightening out to sea to the west. Suddenly I noticed 4 star like lights flying silently to the south east. I thought it was a meteor shower at first but then realised they were not shooting stars. They were in a formation similar to the southern cross but then the one on the botton left moved over to the centre in relation to the others. Have seen on net other reports of strange lights in this part of Majorca, only been here two weeks and already two sightings... Is this UFOs or something to do with electrical storms?/do the UFOs somehow use/generate electro-magnetic energy?
