What is the song called

“A man driven almost insane from not remembering the title of a song overheard a stranger humming its tune”

“Goddammit,” he muttered as he slammed his front door shut behind him. He dreamt about it again. Again. It had been going on for months, those dreams. Then finally he had a week of peace without it, until it started again today. The dream was never the same, but it always had the same background tune. Over and over and over again. Then, as he almost thought of the name of the song, he would wake up and forget it all. Maybe he should just give up on it. But as he thought that, a sharp pain went through his hart. He couldn’t give up. He had to keep going so that he wouldn’t fall apart. So he wouldn’t forget her.

He breathed in deeply, trying to give himself energy, and started walking. “Something with an L… I’m sure of it,” he said to himself. As his full concentration was focused on the pavement, pondering about the song, he didn’t notice a guy twice his size walking straight at him. With full force they walked into each other, bouncing him backwards. His armed mowed through the air as he tried to get a grip on something to keep him straight. Then he felt the huge hands of the guy pulling him back up. Slowly he looked up, and he started shaking as it dawned on him what a massive man it was. A plump, grim face looked down on him, and he could still feel his fingers gripping his arms tight. “I-I’m sorry,” he stuttered out. “I didn’t-“, “Oh that’s alright!” The big guy interrupted him. “I didn’t see where I was going, sorry man,” he apologized. “You steady there?”

That’s when he realized he was still shaking. He cleared his throat. “Yeah I’m good, thanks mate.” And the man let go of his arms. Relieved he took a step back and calmed himself with a few slow breaths. “Alright,” the big guy smiled at him after which he walked of, softly whistling.

That made him freeze in place. That was it. That was the tune. “Wait,” he huffed out. In panic he turned around and started shouting after him. “Wait!” His legs didn’t seem to move fast enough for him to catch up, they seemed to be too heavy. “Wait!” He called out again. He then tripped over his feet and fell forward, but managed to catch himself with his hands before his head would touch the concrete. “Wait…” He whispered again, lying on the floor. As the last notes of the tune fade away, it suddenly came to him. He remembered the name of the song. Tears started streaming down his face and sobbing he laid there, remembering the song. Remembering her. Everything finally came back to him as he at last remembered the song, little-

Sweating and in full panic he shot straight up in his bed. Panting he sat there as he felt the tears still dripping down his cheeks. “Goddammit,” he cried out when he let his face fall into his hands.
