weird dreams..?

I JUST found out I'm pregnant (about 4 weeks!) super early the only symptom I'm having is my emotions are raging all over the last week or so. Last night I felt like I had a terrible nights sleep and my husband told me I freaked him out! Apparently the first time I started talking I asked my husband "is this package for me? Please open for me I wanna see" as i held my hands apart like I was actually holding something! The second time he said I jumped up freaking out saying "there's ants on the bed get them off!" This is totally not like me. Please tell me this is normal for this early hahah I feel like an idiot but I'm curious now 🤔
