The common assumption by many people in any culture is that unseen forces can attempt to speak to people through subtle signs, feelings, and experiences that often are overlooked in the hectic activities of everyday life. Where science would treat such notions with a pinch of salt, psychology and cultural traditions indicate that what can be perceived as communication may be an indication of increased awareness, emotional processing, or a set of involved human instincts that influence the perception of out of the ordinary or significant events by the participants.
Perceiving Uncharacteristic Recurrent Signs

Individuals tend to complain of repetitive symbols, numbers, or patterns that appear to be too good to be disregarded, which may leave them with a solid feeling that something bigger than coincidence is involved. According to experts, these experiences are important and personal because the human brain is programmed to identify patterns.
Experience of Acute Emotional Change

Unaccounted swings in mood that have no obvious cause can be intense and disorienting, causing some to attribute them to an external force or some type of non-verbal communication. According to psychology, emotional memory and subconscious stimuli may appear in a manner that may seem abrupt and drastic.
Listening to Unaccountable sounds

Low tones, low whispers or unclear sounds in quiet places can attract attention and cause curiosity about what is making the sound. These experiences in most occasions are connected to environmental factors or extreme sensitivity to normal background noise.
Feeling The Presence of Stillness

The stillness experienced at some points may create a sense of the presence of something or a person even when one is alone. This feeling is usually connected with a greater sense of alertness and the urge of the brain to stay on high alert in a serene environment.
Objects In Motion Without Reason

The presence of things that seem to move or disappear without any obvious reason can be a puzzling and disturbing experience to the person involved in the situation. But, these incidences are often attributed to lapses in memory, distractions in routine, or unrecognized movement.
Good Intuition of Situations

Such a strong gut feeling of a person or an event may appear as a message that is transmitted outside the normal thinking patterns. According to experts, intuition is the quick processing of past experiences and minor clues by the brain to make quick judgments.
Recurring Imaginations about Another

Thinking about a specific person and having no apparent cause to do so, can be experienced as a relationship more than a coincidence. This is usually emotional attachments or thoughts left unfinished which keep re-occurring in the mind.
Sudden Change in Temperature or Energy

Experiencing certain spaces in unexpected chills or heat may cause inferences of invisible presence or power. Such sensations are usually better attributed to environmental changes, airflow or physical sensitivity.
Discovering Patterns in Accidents

Coincidences that seem to have a disturbing sense of accuracy can be too accurate to be accidental, and invite further thought and analysis. Most scholars perceive this as the brain giving meaning to coincidences so as to form a feeling of understanding and relation.
Interpretation is influenced by Culture

These experiences are interpreted in various cultures through long traditions and define how people interpret what they feel or see. These ideologies offer context and meaning although scientific thinking offers other explanations depending on human perceptions and cognition.
