According to researcher Deidre Barrett, professor of psychology in the department of psychiatry at Harvard Medical School, the most common recurring dreams tend to be negative and may take some work to overcome.

It is enough to have the same dream two or more times for it to be considered recurring and the recurrence can also be distant in time.

Recurring dreams may be related to situations that in real life generate worry, nervousness, traumatic events. Often, however, they can also be linked to other situations. (Source: cnn.com)

Many decades after the end of the Second World War and also the Cold War, we now have the opportunity to enter the historic bunkers used to defend against the threat of nuclear attack.

The secret nuclear bunker at Hack Green in Nantwich, UK, played a key role in the defence of Britain for almost sixty years. The site was chosen during World War II to protect the territory between Birmingham and Liverpool from hostile attack, and also as a location for new radar equipment.

The secret bunker is now privately owned by the Siebert family and is operated as a trust museum.

According to the US Centres for Disease Control and Prevention, when there is a thunderstorm with lightning and thunder you should avoid showering, washing in the bathtub and doing the dishes (source cnn.com).

The reason, according to CNN, is that lightning would be able to travel through pipes and that is why you should avoid contact with plumbing and running water, to avoid the risk of being struck.

The danger with lightning, therefore, is not only present when you are outside but potentially also inside.

Bees play a vital role in the ecosystem, pollinating plants and ensuring food production. Bees provide us with valuable products that have been used for millennia in both cooking and body care such as honey, pollen, royal jelly, propolis, wax, and even poison.

However, bees are threatened from many sources, including habitat loss, pesticide use and climate change.

It is important that we all take steps to protect bees and their environment.

In this photo gallery, we offer eight practical tips to save bees.

History is unfortunately full of episodes in which natural catastrophes have claimed a very high number of victims.

Looking at the case history, among the main causes that have triggered natural disasters throughout history are earthquakes, followed by floods and cyclones. These are natural phenomena beyond the control of man, who often manages to do very little, even in terms of prevention, against them.

The downside of all this is, of course, the high number of victims and the destruction that such phenomena generally entail. Often, in both cases, with devastating effects of great magnitude. (source: livescience)

Each of us may go through moments of uncertainty at work, and recognising these signs could be crucial in preparing for change.

We have explored gestures, behaviours and situations that could indicate a threat to your job position, with the aim of providing awareness and inspiration to react positively in such circumstances.

Some of these situations taken individually may not be indicative of such a drastic consequence as dismissal, but taking a moment to carefully observe each situation and reflect on your personal experience is nevertheless a way to prevent unpleasant situations from occurring.

In some of these cases, however, one is not appreciated and one is not to blame for this: if it happens, it is good to look around for a new opportunity.
