Vivid dreams during pregnancy?

Anyone else get vivid dreams while pregnant? I am 11 weeks pregnant and just started getting them. Mine are so weird. I had two last night. Most of them involve me being pregnant and in some sort of dangerous situation where my unborn child may get hurt. For instance, I was chased by an alligator last night. The other night I got injected with mystery medications that may hurt my baby. Other times I was doing drugs (which I don't do in real life). Strange strange stuff. Anyone else have this happen to them?
