The phrase "you make me feel alive" is a poetic expression of the intense emotions and sensations one experiences when they are around someone they deeply care about or love. It conveys the idea that being with that person brings a heightened sense of joy, happiness, and excitement, as if life itself becomes more vibrant and meaningful in their presence.
When someone says this to another person, they are expressing that the individual's presence and the connection they share contribute to their overall well-being and emotional fulfillment. The phrase is often used to convey the idea that the other person brings out the best in them, ignites their passions, and makes them feel more connected to the world around them.
It's important to note that this phrase is not meant to be taken literally; rather, it is a metaphorical way to describe the strong emotional impact that a significant person can have on someone's life, making them feel more alive and engaged in the experiences they share together.
