Compared to the x37 the dreamchaser looks like a thunderbirds ship or something.

Yeah this has a funny look to it.

Instead of being a space "plane" (fuselage with separate wings & tail) like the Shuttle or other aircraft, the Dream Chaser is a lifting body - the fuselages curvature provides the lift (so no traditional wings) and what looks like wings serve more as an eleven tail like on modern fighters. In short, it flies the same way a frisbee does.
DC is almost all carbon composite and is powered by 2 hybrid rockets as its main thrusters & escape system. Hybrids are a blend of solid and liquid - the fuel is a rubber-like solid casing and the liquid oxidizer is nitrous oxide (laughing gas.) Nitrous also doesn't need to be strored at the deep cryogenic temps of liquid oxygen, and it doesn't boil away over time like LOX. Very different, but proven.
Yes, it has a cockpit and can carry a crew of up to 7, or fly robotically, or both as a robotic crew escape vehicle. It can also land on any conventional airport runway within 1,500 km of its orbital track, a capability known as 'cross range'. It also re-enters at just 1.5G - less than the forces on many kiddie roller coasters, which also makes it good for orbital med-evac. There are also mods being looked at for an airlock and cargo bay with space doors.

yeah its funny looking but I like it if it is cheaper than just using a regular module that comes to the earth via parachute.

… whatever it does up there.
Making adjustments the the Death-ray satellites, no doubt.
