Nope. Just someone who is trying to be creepy, and not succeeding. I suppose Hypno may feed off dreams, but I don't think it would do it in a way. Granted one did not let Lostelle leave, so it is possible I guess.
I feel like Machamp would be odd, also for the weirdos male Gardeivor
Read the pokedex entries. Hypno is almost as sinister as the hypnotoad.
1. If you lock eyes with it, it will try to hypnotize you. It is best to close your eyes quickly before you get hypnotized. 2. Hypno holds a pendulum in its hand. The arcing movement and glitter of the pendulum lull the foe into a deep state of hypnosis. While this Pokémon searches for prey, it polishes the pendulum. 3. When it is very hungry, it puts humans it meets to sleep, then it feasts on their dreams. 4. It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized.
The song lyrics are all stemming off the pokedex entries, which very clearly state that it's sustenance is dreams, that it views it's targets as prey, and that there has been at least one incident with a hypno carrying away a child it hypnotized.
All of which fit in perfectly with the song.
A lot of pokedex entries are surprisingly morbid. We know that caught pokemon eat...pokefood. But what about wild pokemon?

They like to eat gold nuggets. Grave robbers who mistake them for real coffins and get too close end up trapped inside their bodies.
If we have pokemon that track their prey with the intentions of being able to eat all the prey's friends and ones that eat humans and turn them into mummies, what's so far fetched about Hypno?
