This Strange Effect

The speaker describes being powerfully affected by someone they love. At first, the feeling is presented as a pleasant mystery: the other person changes how the speaker sees the world. The lyrics then become more certain, as the speaker recognizes the feeling as love, while still hinting at some hesitation. The repeated refrain emphasizes how strongly they enjoy this connection.

The contrast between “darkness” and “light” suggests that the loved one brings hope, happiness, or clarity to the speaker’s life. Saying that the person makes the world “seem right” implies that things feel better or more settled when they are together. The phrase “strange effect” is not a literal physical effect; it describes an intense emotional influence that the speaker cannot fully explain.

There is a small tension in the line about not knowing whether they “should” feel this way. It could mean the speaker is surprised by the strength of the emotion, or unsure whether giving in to it is wise. The lyrics do not explain the reason for that doubt. Still, the repeated statement that the speaker likes the feeling makes the overall mood joyful and accepting rather than fearful.
