What does "revelation" commonly signify?

"Revelation" commonly signifies an awakening to the truth, which reflects the fundamental idea behind the term. This concept often relates to a moment of insight or understanding where an individual becomes aware of something previously hidden or obscured. In many contexts, particularly philosophical and religious ones, a revelation can lead to profound insights that dramatically change one’s perspective or belief system.

The other options don't fully encapsulate the broader meaning associated with revelation. A hidden truth suggests something that is concealed but doesn't necessarily imply the awakening aspect. A recurring dream relates more to the experience of dreaming rather than a moment of clarity or insight. A scientific theory involves a systematic explanation based on evidence and experimentation, which is not aligned with the essence of revelation as an experience of newfound understanding. Therefore, the choice that best represents the concept of "revelation" is the awakening to the truth.
