Kaleidoscope Dreams

[UnicornRainbowCake]

I lollop on my bed,
An arena of dreams. 'Lollop' and "arena' don't fit in with each other well. Lollop is childlike/clumsy, but arena has connotations of crowded, gladiator fighting kind of violence.
I rest my head,
Eyes burst at the seams. This just seems cliche

A mirage of bright colours, Is mirage the right word to use?
Arranged in a pattern,
The beauty, it smothers,
I’ve landed on Saturn. Well that was one hell of a twist

The brightness goes dim, Wait. What about Saturn? Does Saturn go dim? Why are we on Saturn? How did you get to Saturn? Unanswered questions
I start to begin, Change of rhyming scheme at the end? I'll presume it was deliberate
To realise I’m home So you live on Saturn or you've gone home to Earth?
Engulfed in foam. Is this an allusion to something? It doesn't link to anything else in your poem

This isn't all negative - you've used punctuation and grammar correctly, and most of your rhymes are rhymes. I would repost in novice as it needs quite a bit of work before being in serious. You have used techniques correctly, but not to an enhanced effect. Your line breaks are there because it makes the rhyming work, but it doesn't enhance your poem. As ever, this is just what I think and I have understood your poem as.
