# What is it that birds dream of?

For as long as I can remember, I've had this dream.
Let me reassure you, it's a dream many have seen.

I rise above this terrestrial sphere onto a higher plane.
Given this incredible power, I break out of my chains.

How far will I be able to travel? Only my mind limits me.
To have bestowed upon me this incredible gift, a hero I'll be.

What is my dream?

Edit (note, I looked at hexomino and QuantumTwinkie's answers, they both, along with the comment's throughout, helped a lot. Go up vote them :-)):

It's:

Space Flight

For as long as I can remember, I've had this dream. Let me reassure you, it's a dream many have seen.

People dream of flying through space (movies and shows have been made about the dream).

I rise above this terrestrial sphere onto a higher plane. Given this incredible power, I break out of my chains.

Break the chains of being stuck on Earth

How far will I be able to travel? Only my mind limits me. To have bestowed upon me this incredible gift, a hero I'll be.

You have a vast, unexplored area to explore

Bonus:

The title -> Bird's are limited by Earth, they may dream of flying through space Acrostic -> fly through space

Original Guess:

Superman

• Not a bad guess, but the answer isn't a person. – Joe-You-Know Sep 28 '18 at 14:36
• @Joe-You-Know is it just ROT13(fcnpr-syvtug)? – eye_am_groot Sep 28 '18 at 14:58
• You've got it! That's what I was looking for. Although Wikipedia lists it without the hyphen. – Joe-You-Know Sep 28 '18 at 14:59
• @Joe-You-Know yay! Edited! – eye_am_groot Sep 28 '18 at 15:03
• Great edit! You really got what I was looking for. – Joe-You-Know Sep 28 '18 at 15:04

Edit: Given OP's comment on my answer, I think the answer may be

Rocket

Space (or perhaps Outer Space)

A lot of the reasoning remains the same.

Acrostic

Spells FLIGHT

Title

It would be even above what a bird could reach so may be what they dream of

For as long as I can remember, I've had this dream.
Let me reassure you, it's a dream many have seen.

Many people have dreamed of becoming astronauts

I rise above this terrestrial sphere onto a higher plane.
Given this incredible power, I break out of my chains.

Reaching into outer space would break free from the atmosphere (terrestrial sphere)

How far will I be able to travel? Only my mind limits me.

Space is very large, possibly infinite.

To have bestowed upon me this incredible gift, a hero I'll be.

Astronauts are lauded as heroes, think the moon landing.
Also Rocketman, the famous Elton John song.

• Your line of reasoning is right (for this is what limits birds). However, the answer is how they move through your answer. So, you're really close. – Joe-You-Know Sep 28 '18 at 14:46
• I've edited the answer now, not sure if this is what you're looking for. – hexomino Sep 28 '18 at 14:48
• This is more the object that can provide the answer. (You're super close). Wikipedia has a page dedicated to it. I told QuantumTwinkie that his original answer was part of the answer. – Joe-You-Know Sep 28 '18 at 14:56

Are you

Wings

For as long as I can remember, I've had this dream.

You need wings to fly.

Let me reassure you, it's a dream many have seen

People have tried.

I rise above this terrestrial sphere onto a higher plane.

In a higher "Plane"!

Given this incredible power, I break out of my chains.

People have never flown themselves

How far will I be able to travel? Only my mind limits me.

Mars? Maybe Kepler-186f?

To have bestowed upon me this incredible gift, a hero I'll be.

Bird-man

Acrostic

Flight

Title

Birds have wings to fly.

• It's most certainly part of the answer. But I'm looking for something even more liberating than this (or more accurately, it's an even greater form of travel) – Joe-You-Know Sep 28 '18 at 14:35
• No, your first answer is much closer (or that is to say it's a form of movement). The title you can take literally. What is it that birds dream of if they can already fly? – Joe-You-Know Sep 28 '18 at 14:39
• A nice edit, but not what I was looking for. – Joe-You-Know Sep 28 '18 at 14:50
• That's the closest you've gotten so far. – Joe-You-Know Sep 28 '18 at 14:54
• You can theoretically achieve the answer by using either of those. – Joe-You-Know Sep 28 '18 at 15:01

I think it's

flying

because

it's a common dream

and

it involves physical rising from the terrestrial plane (the ground) into the sky

and

superheroes & birds both fly

Is it

FLIGHT

It fits the clue, and it is an

acrostic

of the question.
